Can we help you?

Originally developed to measure agricultural water runoff, H flumes have a "V" shaped design that allows for measurement of a wide flow range. 

Often used to measure irrigation water, snow melt, holding pond overflow, industrial process discharge, and sanitary/storm sewer discharge.

HS Flumes are designed to measure very small flows with a high degree of accuracy; please refer to HL Flumes for large flows.
