Compact Engineering Inc. designs OEM flow switches, OEM level switches, and OEM temperature switches. The flow switches are used for water, air, and electronics applications, and are available as angle body, wire receptacle, low flow, straight body, and indicator types. The temperature switches can serve as low temperature switches or high temperature switches in six narrow differential, preset set points.

Fluid Components International manufactures OEM flow switches and OEM level switches. The flow switches feature stainless steel construction and an industrial design with no moving parts and negligible pressure drop. They are used in liquids, gases and slurries; and suited for low flow pump protection, monitoring lube oil, detecting seal leakage, verifying analyzer flow, and monitoring cooling water. The level switches are used to provide point detection in liquid/gas, liquid/liquid, liquid/foam, and foam/gas interface applications.

Flow Network is a supplier of OEM paddle flow switches with an integral T-piece. Switch specifications include: maximum pressure of 1450 or 3600 psi, switching range of 0.9-1.3 GPM, maximum temperature of 230F, and fittings of 1/4-1-1/2 NPT.

Vertically-mounted, vane-operated flow switches distributed by SOR Inc. are for plant and OEM applications. Featuring top mount design, the switches offer pressure from vacuum up to 1500 psi and temperature from -40F to 400F. The switches are available with CSA, GOST, ATEX, and ASTM material certifications.
