Liquid Types?

Virtually all commonly used clean liquids.

Liquids with small quantity of tiny particles may also be applicable. Particle size should be less than 75um, particle concentration less than 10,000ppm.?

Liquids should contain no or very minor air bubbles.

Examples are chilled/hot water, sea water, waste water, chemical liquids, oil, crude oil, alcohol, beer, etc.

Liquid Temp

(0C - 160C) for clamp-on transducer. Higher temperatures can be accommodated. Consult the manufacturer for assistance.
