High-precision Water Level Meter

Product description

It is built on the latest-generation microcontroller platform of MULTISENSING, which can meet extremely high precision requirements and increase the compatibility with various interfaces. In addition to pressure (level) information, the digital interface also transmits other water parameters such as temperature and conductivity. A solid interface and barometer are designed, which can support up to 1.4KM cable transmission, support Modbus protocol, and have good compatibility, which is convenient for users to use in large-scale networking.

The product has good stability, high precision, low power consumption, and small size. It uses a high-stability pressure sensor as the sensing element. The output data undergoes internal intelligent linear correction and temperature compensation. and high stability requirements. Multiparameter probe with pressure, temperature, and conductivity sensors (CTD – Conductivity, Temperature, Depth) , are approximately 240 mm long.
