Product Introduction
The MT200 level difference meter can be used to measure the height difference between the liquid levels or material levels of two different containers. The most common application is at the water inlet of a sewage treatment plant, where it measures the water levels before and after the coarse and fine screens, calculates the height difference of the water levels, and uses it to start the reverse rake type screen to remove the garbage. The MT200 level gauge can also directly measure the level height of two containers and simultaneously output two analog signals. This application can be used as a dual-channel level gauge and is compatible with the entire series of HEWAY sensors, with a maximum range of up to 50 meters.

Typical applications
Municipal sewage treatment plants, waterworks, power plants and washing sites, various storage tanks, lift pumping stations, etc

Functional characteristics
■ RS485/RS232 communication and isolated 4-20mA analog output.
■ Echo intelligent recognition technology and temperature gradient compensation technology effectively resist various interference signals.
■ Display liquid level, liquid level difference, current and relay status, etc.
■ Intelligent Chinese and English display menu, multiple display modes, and simple operation.
