Welcome to

The patented WATER MONITOR air operated float switch is wholly designed and manufactured in Australia to comply with stringent coal mining regulations.

Four models are available, one is Fire Retarded Nylon with an Anti-Static (FRAS) rear housing, another is the standard Polypropylene model with an anti-static rear housing to provide continuity to FRAS hoses required in coal mines. The third is a yellow nylon model with improved porting for higher CFM where required. The fourth is the Water Hole Monitor which has been designed for nuisance water holes and is tolerant to flowing water and turbulence.
