HPT675 Remote Water Level Data Logger

Remote water level data logger is a self-dissolving data logger. Based on a titanium alloy casing and a lithium battery power supply design, it can be immersed in liquid for more than 10 years for a long time. The built-in temperature sensor can be used to monitor the depth, pressure and temperature of groundwater.

Application :

●Groundwater or surface water level monitoring

●Marine Environmental Engineering Project

●Flood control system or flood control level monitoring

●Real-time monitoring of the liquid level in the tank

●Industrial control system and on-site liquid level monitoring

Advantages
01Self-dissolving structure, without the trouble of cable entanglement.
02Monitor liquid level, pressure and temperature data at the same time.
03Titanium alloy shell sealing structure can be used for corrosive medium.
04Full range digital calibration, temperature error compensation in the whole temperature zone.
05RS485 interface MODBUS-RTU standard communication protocol can be used in DCS or PLC system.
06Measurement accuracy is up to 0.05% FS and low-power lithium battery power technology.
