How It Works
Max H-Series Precision Flow Meters are positive displacement helical meters that are able to operate over a wide range
of ow rates and uid viscosities. High accuracy measurement is achieved through precision machined helical rotors
that move proportional to the ow. High resolution outputs are produced by measuring the direction and speed of
the helical rotors and converting the signals to analog or frequency outputs. Flows can be monitored from 0.1 liters/
min. to 500 liters/min. with uid temperatures from -40°C to 225°C and pressure ratings of 500 psi (35 bar) and 3500
psi (240 bar) depending upon the model. Helical ow meters are especially suited to measuring variable viscosity and
high viscosity uids ranging from 3 cps to 1,000,000 cps. The industrial meter electronics are protected against water,
dust, and most corrosive liquids. The 5-pin Turck connector provided is IP68.
Additionally, IP66 rated explosion proof
enclosures, combined with a choice of one-part and two-part, high temperature designs with remote electronics cover a
wide range of application environments – from the laboratory to harsh industrial processes.
Optional seal materials allow
for different uid compatibility.
Max Machinery, Inc. designs, manufactures, calibrates, and refurbishes high accuracy, high resolution, precision liquid
ow meters under an ISO 9001:2015 certied quality management system. All Max Precision Flow Meters are tested
and calibrated in our lab and provide measurements traceable to NIST. If your calibration certicate is lost or missing,
contact MMI with your meter serial number for a copy.
