CYW26Y Deep Well Input Liquid Level Transmitter Measuring Range 0~200~2000mH2O Underground Water Level Monitoring
The outer diameter of the CYW26Y deep well input liquid level transmitter is only 19mm, and it can measure both liquid level and temperature simultaneously. The anti condensation process design extends its service life. In addition, the internal circuit enhances anti-interference processing, effectively reducing the interference of the water pump, making it an ideal product for deep well water level measurement.
