The smart level differential pressure transmitter is a local transmitter installed on pipes or vessels directly,its isolating diaphragm contacts with liquid medium to directly measure liquid level, pressure and density of high temperature, high viscosity, easy crystallization and sediment, and corrosive medium, then converts these parameters into 4~20mA DC signal output. Level transmitter is widely used in the occasion of measuringand controlling liquid level of river, groundwater level, reservoirs, water towers and containers etc. which is a sensor that converts liquid pressure into liquid level.
