Brooks Instrument MT 3750C Flowmeter

The Brooks Instrument MT3750C Ar-Mite Low Flow Armored Flowmeter is a rugged metal-tube, variable-area flowmeter designed for precise, durable low-flow measurements in high‑pressure, high‑temperature or hazardous processes. The MT3750C uses a 316L stainless‑steel metering tube and 316L end fittings, with a 316L float and Viton O‑rings, and offers multiple connection options (1/4" to 3/4" NPT female or 6 mm tube compression) to fit existing piping; it is a cost‑effective replacement for glass‑tube meters. Rated for a maximum fluid pressure of 1500 PSIG (100 Bar) and a maximum fluid temperature of 204°C / 400°F, it supports a typical 10:1 rangeability across most sizes. Optional transmitter configurations provide a 4–20 mA output for process control, and alarm features include one or two inductive switches or reed switches with IP65/NEMA‑4X protection on alarms and IP66/67/NEMA‑4X on transmitter variants. For systems requiring valve control, Brooks offers cartridge or NRS valves as options. The MT3750C embodies Brooks’ Ar‑Mite low‑flow lineage in a compact, armored metal‑tube meter built to withstand demanding industrial environments while delivering reliable flow measurement across a range of liquids and gases.
