Input type smart level meter

Principle of input type smart level meter

Input type (Hydraulic pressure) liquid level transmitter adopt high performance diffused silicon piezoresistive pressure sensor as measuring element, after the high reliability of amplification circuit and precise temperature compensation, convert the gauge pressure or absolute pressure of the measured medium into standard voltage or current signals.

This product has the advantages of small volume, convenient use and installation, directly put into the water, that can measure liquid height from the surface to the end of the liquid level transmitter.

Safe Use of input type smart level meter

When measure static liquid level in an open container, put the liquid level transmitter directly into the bottom of the container, just use nylon belt or triangular adjustable mounting frame to fix the cable(junction box) in the open position of container.

When measure liquid level in flow liquid, because the medium has a large fluctuation, we can insert one φ45mm steel pipe, and punch several holes on the pipe wall on the opposite side of the flow direction the in different heights, then let the liquid flow into the pipe. Another method is to equip the damping device at the bottom of the liquid to filter sediment and eliminate the infulence of dynamic pressure and wave.
