The radio frequency admittance level switch, also known as the radio frequency admittance level meter, is a radio frequency admittance measurement technology developed based on the capacitance switch measurement technology. The capacitance value between the probe and the storage tank changes due to changes in the medium. When this change value reaches the set value of the switch, the switch signal output is converted, and the alarm bell, electromagnetic valve, or other low-power equipment can be operated to alarm and measure the material level. Due to its evolution as a capacitive switch, it can overcome the shortcomings of capacitive level gauges and is widely used in industrial level measurement such as petroleum, chemical, metallurgical, power, food, papermaking, building materials, etc. It is highly trusted by users. However, radio frequency admittance level gauges are not versatile instruments. In order to use this level gauge reasonably, familiarizing oneself with its advantages and disadvantages can better discover the appropriate space for use.Advantages of RF admittance:1. High cost-effectivenessThe strong functionality and relatively low price of the product make it more cost-effective compared to similar instruments and meters2. Minimal measurement errorDue to the fact that the radio frequency admittance level switch is not affected by hanging materials and environmental changes, its measurement results are more accurate. Moreover, the components of the radio frequency admittance level switch have no moving parts during the measurement process, so there is no mechanical damage. This makes the radio frequency admittance level switch unnecessary for regular maintenance, high accuracy, and long service life.3. Wide universalityThe radio frequency admittance material level switch can withstand high temperature, corrosion, explosion-proof, anti hanging, material impact, friction, and is easy to maintain. This product is widely used in the measurement of coal ash, solid particles, and adhesive materials in petrochemical industry, power plant dust removal and ash hopper, storage bin, and measurement of coal ash. Disadvantages of RF admittance:Due to the influence of its measurement principle and product structure, the RF admittance level switch may have the following drawbacks in use:1. There are requirements for the dielectric constant of the mediumThe radio frequency admittance level meter requires the measured medium to have electrical characteristics, and can only measure the dielectric constant of the medium ≥ 1.6 in order to achieve measurement2. Need to work in a medium stable environmentDue to the need to calibrate the parameters of the RF admittance level switch based on the medium to be measured after installation, this instrument cannot measure smoothly in a working environment where the medium is frequently changed.3. Cannot be used in compact measurement environmentsDue to the anti hanging product characteristics of the RF admittance material level switch, the probe needs a certain length and cannot be too short. It needs to be used in situations where the insertion depth is ≥ 250mm, so it is not suitable for compact measurement environments.

Level meter is a widely used liquid level measuring instrument, which uses microwave signals to measure the height of the measured object with high accuracy and stability. In the process of using level meter, the choice of connection method has an important influence on the accuracy and safety of level measurement. This paper will popularize the connection methods of radar level meter, introduce the characteristics and application range of each connection method in detail, and combine them with radar level meter in depth.First of all, flange connection, flange connection is a common connection method of radar level meter, which is applicable to various sizes of ships or pipelines. The flange connection requires the flange of the level meter to be connected to the flange of the vessel or pipeline and fixed by bolts. Flange connection has the characteristics of easy installation and good sealing, and can adapt to the measurement of various media. When using flange connection, care needs to be taken to select the appropriate flange specifications and materials to ensure the sealing and load-bearing capacity of the flange.The second type of threaded connection, the threaded connection is a common type of level meter connection for small vessels or pipelines. The threaded connection requires the threads of the level meter to be connected to the threads of the vessel or pipe, which are held together by thread tightening. Threaded connections are easy to install and have good sealing characteristics, and can be adapted to the measurement of small vessels or pipelines. When using a threaded connection, care should be taken to select the proper thread size and material to ensure the sealing and load-bearing capacity of the threads.The third type of clamp connection, a clamp is a ring-shaped clamping device that secures the level meter to the outer wall of a pipe or vessel. A clamp usually consists of two semicircular parts connected by a bolt or quick device in the middle. During installation, the clamp is placed over the pipe or vessel, the two semicircular parts are put together, and then the level meter is clamped into the clamp, and the level meter is fixed by adjusting the tightness of the clamp. The clamp connection has the features of easy installation and easy disassembly, and is suitable for the level measurement of small pipes or vessels. It can adapt to the measurement of various media, and the installation process is simple and quick. However, compared with other connection methods, the sealing of clamp connection may not be as good as other connection methods, and it needs to be selected according to the actual situation and strengthen the protection measures.The fourth type of insertion connection, the insertion connection is a special type of level meter connection for certain special vessels or pipes. The plug-in connection requires the probe of the level meter to be inserted inside the vessel or pipe and held together by a fixing device. The plug-in connection is easy to install and adaptable to various shapes and sizes of vessels or pipes. When using the insertion type connection, care needs to be taken to select the appropriate probe material and length to ensure the stability and accuracy of the probe.The above four connection methods are common radar level meter connection methods, and their selection needs to be based on the actual situation. Whether flange, thread or other connection methods are for the instrument and working conditions. The main thing is to give full consideration to the working conditions, according to the working conditions to choose the specific connection method.

What is a vortex flowmeter?A volume flowmeter that uses the Karman vortex principle to measure the volume flow rate or mass flow rate of liquid gas vapor is called a vortex  flowmeter. 1、 Installation requirements for external environment of vortex flowmeterWhen the vortex flowmeter must be installed outdoors due to operating conditions, it is necessary to install lightning protection, rain protection, and sun protection devices to ensure the service life of the instrument, and a filter must be installed in front of the straight pipe section where the flowmeter is installed. The ideal place for installing vortex flow meters is a place that is free from electromagnetic interference, thermal FU radiation, and easy to repair and disassemble. Do not share a ground wire with a strong current system and must be reliably grounded.2、 Installation requirements for bypass pipes of vortex flow metersStop valves and bypass pipes should be installed before and after the pipeline installed in the flow meter. The downstream of the flow meter pipeline is where the flow control valve is installed. The reason why the stop valve of the upstream pipeline is not suitable as the control valve is to avoid unstable flow of fluid in the upstream part.3、 Installation requirements for piping of vortex flow metersThe inner diameter of the pipeline installed in the flowmeter should be the same as the inner diameter of the upstream and downstream piping.4、 Requirements for straight pipe sections of vortex flow metersThe flow meter must be installed horizontally on the pipeline (with a slope of less than 50), and the axis of the vortex meter should be concentric with the pipeline axis during installation, and the flow direction should be consistent. The upstream pipeline length of the flowmeter should have an equal diameter straight pipe section of no less than 2D. If the installation site allows it, it is recommended that the upstream straight pipe section be 20d and the downstream straight pipe section be 5d.Before installing the flow meter, debris, welding slag, stones, dust, etc. in the pipeline should be cleaned. It is recommended to install a filter with a 5-micron sieve upstream to block liquid droplets and sand particles. When the flow meter is put into operation, the front valve should be slowly opened first, and then the rear valve should be opened to prevent instantaneous airflow impact and damage to the turbine.Want to knon more about what is vortex flow meter, contact Kaidi Sensors, a professional vortex flow meter manufacturer.

Magnetic Sensitive dual color Level Gauge instruments can be used for medium level detection of various towers, tanks, tanks, spherical containers, boilers, and other equipment. This series of magnetic type level gauge can achieve high sealing, leak proof, and suitable for high-temperature, high-pressure, and corrosion-resistant situations. It compensates for defects such as poor clarity and easy breakage of glass plate (tube) level gauges, and there is no blind spot in the entire measurement process, with clear display and a large measurement range.Magnetic Sensitive dual color Level Gauge is an instrument with high measurement accuracy, specifically used in the chemical industry to measure liquid levels and ensure real-time observation of liquid level data. Nowadays, there are more and more manufacturers using Magnetic Sensitive dual color Level Gauge. People have also found many problems in the use of Magnetic Sensitive dual color Level Gauge. For example, when using Magnetic Sensitive dual color Level Gauge, they often encounter false liquid levels, which can seriously affect the actual measurement accuracy. Many people are not particularly familiar with the cause of this problem and do not know how to solve it. The solution is as follows:When using a Magnetic Sensitive dual color Level Gauge for measurement, both the gas and liquid phases should be connected. If there is a false liquid level phenomenon, we can first check if there is a disconnection in the gas and liquid phases. There are many methods we can use. Firstly, we can use a magnet to scan along the surface of the Magnetic Sensitive dual color Level Gauge, and you will roughly see the corrected state. If the Magnetic Sensitive dual color Level Gauge is not measuring a dangerous liquid, we can first release its liquid phase and then continue with the above operation, using a magnet to correct it. Of course, the occurrence of false liquid levels may also be due to the presence of a large number of interference factors in the surrounding area, resulting in inaccurate measurement of the Magnetic Sensitive dual color Level Gauge. We need to first investigate the surrounding environment. If there are obvious sources, magnetic field interference, and heat source interference, we need to promptly investigate and eliminate them. The signal distortion of the magnetic level gauge with transmitter is also an important reason, and the failure and looseness of its wave guide wire are the key reasons for signal distortion. We can also check the internal wave guide wire parts more frequently and promptly replace them if any damage is found.The above is an explanation for the problem of false liquid level when using a Magnetic Sensitive dual color Level Gauge for measurement. If we encounter such a situation in actual use of a Magnetic Sensitive dual color Level Gauge, we can also try to solve it ourselves. There is still a lot of knowledge about the use of Magnetic Sensitive dual color Level Gauge, and everyone should learn and train their skills in advance during their daily use.
