Originally developed to measure agricultural water runoff, H flumes
have a "V" shaped design that allows for measurement of a wide flow
range. Additionally, H flumes are used to measure irrigation water, snow
melt, holding pond overflow, industrial process discharge, as well as
sanitary and storm sewer discharge.

Model HS flumes are designed for the measurement of very small flows
with a high degree of accuracy. Model HL flumes are designed to handle
very large flows.

Rather than try to make the flow application fit a particular type of
flume, we carefully analyze the parameters so we can select an
appropriate flume for the application. Options and modifications are
available to ensure that the customer’s requirements are fully met, and
that additional instruments are easily interfaced with the flumes.
