Liquid level transmitter selection instructions

Liquid level transmitters are commonly used instruments in industry, so how to choose a suitable liquid level transmitter? 1. Signal output requirements, the general output signal is PLC, DCS or instrument and other devices, then the output signal of the liquid level transmitter must match the input signal of these devices. Common output signals are 4-20mA, 0-20mA, 0-10V, 1-5V and other analog signals. Second, the power supply, the liquid level transmitter needs power supply, the commonly used working power supply is 24V-dc, 220V-ac, the less commonly used power supply is 12V-dc, 15V-dc, 48V-dc, 110V-ac and so on. 3. Installation method: The liquid level transmitter generally adopts screw installation or flange installation, and the wiring adopts terminal wiring type, which is installed on the instrument. 4. Accuracy requirements: Analyze the specific situation and see if the accuracy is applicable; 5. Occasion requirements: For example, their specific application fields and scopes, such as power plants, chemical plants, etc. 6. Size requirements: The design of the liquid level transmitter is becoming more and more miniaturized, and the purpose of miniaturization is to occupy less space. Of course, users should be allowed to install densely, but there is a heat dissipation problem in dense installation, so the internal power consumption must be reduced. Therefore, the value of internal power consumption should also be paid attention to when selecting. The externally mounted liquid level gauge is a non-contact liquid level gauge using ultrasonic measurement technology. No need to open holes, the ultrasonic probe can be measured by sticking to the bottom of the storage tank. There is no limit to the pressure in the container. It can measure flammable, explosive and strong corrosive media. It is easy to install and does not need to stop production.
