Double flange remote liquid level gauge

It is connected to two copper capillary tubes at the pressure tapping ports of the positive and negative chambers of the differential pressure transmitter, with two membrane boxes sealed with stainless steel membranes and fixed on the installation flange at the ends. The positive and negative pressure chambers of the membrane box, capillary tube, and differential pressure transmitter are filled with silicone oil using vacuum filling method, and they are tightly connected with outer nuts, connecting pipes, and joints. In this way, when measuring the liquid level, the pressure sensed by the stainless steel corrugated diaphragm on the pressure sensing box is transmitted from the silicone oil to the positive and negative pressure chambers of the differential pressure transmitter.
