In a variety of different scenarios of smart water, water level meters often appear, and it is a very common sensing
layer device.
The water level meter can accurately monitor the water level change by measuring the height of the liquid, which provides important data support for the smart water system. With the increasing demand for water level parameter in municipal, pipe network, hydrology, water conservancy, joint displacement and adjustment departments, water level gauges have also begun to become more intelligent. Due to the use of water level gauge to contact water for a long time, so the material, precision requirements are also
relatively high. The remote water level meter developed by Tangshan Landi can be applied to water level monitoring.
Telemetering water level meter is a highly integrated intelligent telemetering water level meter, including telemetering terminal and sensor two parts, is a set of signal acquisition, data storage, wireless data communication and other functions in one intelligent telemetering terminal equipment. With low power design circuit, it can collect standard transmitter signal or analog signal output of instrument, level signal, dry
contact signal, pulse signal and so on.
Tangshan Landi remote water level gauge - waterproof small steel gun, the use of quality materials and precision manufacturing process, to ensure its excellent performance in harsh environments. Whether it is in a wet basement or in a rainy outdoor environment with high waterproof requirements for equipment, it can maintain long-term stable operation.
