Longview Marine is a distributer of Rongde system, which supply series of product such as Pressure, Temperature, level Monitoring and Alarm System, Valve Remote Control System, anti-corrosion and Pollution Prevention System, Fire Extinguishing System, , Magnet Coupling and Permanent Governor, Intelligent Monitoring and Alarm system and its spare parts.
The device can be used for measuring the liquid level of fresh water, seawater, fuel tank, quadrangle draught, etc. In order to prevent the corrosion of the liquid medium, the material of the sensor is anti-corrosive, thus prolonging the service life and reducing the later maintenance.
Summary :
The pressure level sensor can be used to measure the level of fresh water, sea water, fuel tank, four corners, etc. In order to prevent the corrosion of liquid media, the material of the sensor is anti-corrosive. The working principle is to convert the liquid pressure value induced by the diaphragm into a corresponding signal value and send it to the control display system for processing and display.
