Compare with level sensors, which continuously measure the change in level, the level switch wholesale only indicates whether or not the level has reached a certain height. A detector therefore does not send a signal proportional to the level but a switching signal.

The tuning fork level sensor is a level measuring instrument based on the vibration principle of the cantilever beam, using the tuning fork as the vibration probe, and using the piezoelectric device to realize the drive and detection of the vibration of the fork body.

With the rapid development of my country's chemical industry, the petrochemical industry, as an extremely important part of the chemical industry, has been able to continue to develop and progress, but the original artificial magnetic liquid level gauge flushing form cannot adapt to its development, and there are many shortcomings in manual measurement.

The radar level gauge has the following measurement characteristics: ① The measurement results are highly accurate, because the radar level gauge is not easily disturbed by external factors during actual measurement, so the data measurement results are accurate

At present, the demand for crude oil reserves is increasing, the quantity of crude oil is constantly increasing, and higher requirements are also put forward for the performance of oil storage tanks. Liquid level, an important production data of oil storage tanks, is measured when measuring the liquid level. The final measurement result needs to have extremely high accuracy, and the previous manual measurement form has many drawbacks.

For condensate recovery applications, guided wave radar (GWR) transmitters and magnetic level indicators provide reliable, efficient level measurement.

Level switches, like level sensors, are mainly used to determine the filling level in tanks, silos or storage containers.In contrast to level sensors, which continuously measure the change in level, the level switch only indicates whether or not the level has reached a certain height. It is a one-time measurement. A detector therefore does not send a signal proportional to the level but a switching signal.

A electromagnetic flow meter is a volumetric flow meter which does not have any moving parts and is ideal for wastewater applications or any dirty liquid which is conductive or water based.

The ultrasonic flow meter is used to measure the flow rate of the fluid and it is done with the help of sound waves. The sound waves will be transmitted to the liquid and these waves would be reflected back from the particles or bubbles in the fluid.

Turbine flow meter consists of a multi-blade rotor mounted with a pipe perpendicular to the fluid flow.

Demands for increased safety and improved efficiency in processing facilities have made the magnetic level indicator an indispensable level control device.

From single-use to magnetic to variable-area, the options in flow meters are plentiful. But there are distinct differences in functionality, accuracy, and certainly price. Ultrasonic sensors that accurately and non-invasively measure through commonly used tubing is an excellent multi-use option that is positioned on the higher end of the price scale.
