MT3750 Series

MT3750 Series Metal Tube Variable Area Flow Meters

Accurate low-flow measurement. Long-lasting performance in harsh environments.

Models 3750C

Need reliable, durable flow measurement in high-pressure, high-temperature or hazardous process settings? The MT3750 metal tube variable area low flow meter from Brooks Instrument is your hard-working answer.

Constructed from high-strength steel, the MT3750 Series VA low flow meter features a compact design and multiple threaded and flange connection options to make it easier to install and integrate into existing plants, as well as a cost-effective replacement for glass tube flow meters. Certified explosion proof, our low flow liquid flow meters also offer optional transmitters or inductive alarms for more advanced flow measurement and process data capture operations.

Features

Low flow ranges: Up to 100 I/h or 26 gph
High pressure and temperature rating
Compact size
Multiple threaded or flanged connections
Large, easy-to-read indicator
No external power required
Optional accessories include needle valve, flow controllers and alarms
Available with 4-20 mA flow signal transmitter, and/or reed switch alarm signals or inductive alarms for high/low-flow conditions

Benefits

Engineered for repeatable accuracy in low-flow rate applications with high-pressure or hazardous fluids
Stainless steel construction and compact size enables easier installation into tight spaces, hazardous environments or remote areas
Compatible with a wide range of liquids and gases
Multiple connection types enable use in multiple location in one plant or process
Optional alarms, transmitters and limit switch controllers provide added levels of measurement and control
Great replacement for glass tube flow meters (same lay length as Sho-Rate Series 1350)

Applications

Basic liquid or gas flow measurement
Rotating equipment flow measurement
Process analyzers
High-pressure flow on offshore oil platforms
Burner control
Gas chromatography
Chemical injection
Purge liquid or gas metering
