The float level transmitter has the advantages of simple structure,convenient debugging, good reliability and high precision. It is widely used in continuous measurement of liquid level (interface) of high pressure, viscous, dirty, corrosive and other medium. It can support 0~5VDC/0~10VDC or 4~20mA standard signal output, the transmitter adopts 24VDC twowire type, the working is stable and reliable, no need to adjust.
It can be used in open, airtight containers or underground pools, and can be displayed on site, or can be displayed and controlled in the control room with instruments. It can measure conductive and non-conductive media, and can overcome the influence of false liquid level caused by liquid foam. It is widely used in oil refining, chemical industry, paper making, food, and sewage treatment industries.
Measuring Principle
The floating ball liquid level transmitter uses the magnet in the floating ball to change with the liquid level to change the voltage divider circuit composed of the resistance in the connecting rod and the reed switch. The voltage division signal is converted into a 4-20mA standard signal through the converter. Display the actual position of the liquid through the display instrument, so as to achieve long-distance detection and control of the liquid level.
