Perhaps you recognize ageless Mercoid pressure switch. No longer available with mercury switches, these are still popular with snap-action SPDT circuits in GP, NEMA4X and Explosion-proof housings.
Dwyer also makes a submersible level transmitter that is quite good for measuring the level in a wet well. Wired into the MPC pump controller, a digital display and pump alternation is now available at a very low cost.
The W E Anderson division of Dwyer Instruments manufactures their V4 Universal flow switch for detecting flow or no flow in pipes from 2 inches and up. Vanes are made of 316 stainless steel and switch bodys can be brass or stainless.
For smaller pipes we recommend the V6 shown at left. Both the V4 and the V6 are explosion-proof and FM approved.
