These diaphragm-operated liquid level controls are available with either a pneumatic or electrical control switch. The INVALCO Model CADMEX-201 is supplied with an explosion- proof SPDT Micro Switch. This switch is UL and CSA approved. The Model CADM-201 is supplied with the popular snap-action, three-way Micro Valve®, ideally suited for diaphragm motor valve control. The 2″ process connections are recommended where high paraffin or sediment content is present in the measured material. The most outstanding feature of these controls is the absence of troublesome small orifice and chambers usually found in similar types of floatless level controls.
