OTT PLS pressure water level meter adopts dry ceramic capacitance sensor and micro-processing technology design, with SDI-12 interface or 4 ~ 20mA output optional, the output value includes water level and temperature measurement;
The instrument comes with an air duct, which is connected to the outside atmosphere through the air duct, and the other end is connected to the pressure sensor. The pressure sensor measures the water pressure and the external atmospheric pressure at the same time, and directly obtains the actual water pressure through the pressure difference method, and then converts it to the corresponding water column height, and outputs it to the external data acquisition instrument in the form of water depth or water level.
The microprocessor built into the measurement unit eliminates the effects of changes in water temperature or density. The measurement accuracy is as high as 0.05mm, and it can also compensate for the impact of gravity acceleration changes at different altitudes and latitudes.
The overload capacity of the sensor is 10 times of the full range, and the protective tube is welded by laser to ensure the waterproof effect. At the same time, it has excellent cost performance.
Various surface water level measurement, groundwater level measurement, long-term water level measurement and other applications that require water level measurement.
