Dwyer RMA-4-TMV | Rate-Master Flowmeter | 0.5-5 SCFH Air, 2" Scale, Top-Mounted Valve
The Dwyer RMA-4-TMV is a Rate-Master flowmeter that reads 0.5-5 SCFH air directly on a 2" (51 mm) scale and comes with a top-mounted valve. Suited to general-purpose gas and liquid flow indication, the RMA-4-TMV can be surface or panel mounted.
- Range 0.5-5 SCFH air on the 2" (51 mm) scale, top-mounted valve fitted
- 4% accuracy and 1/8" female NPT process connections on the RMA-4-TMV
- RMA-4-TMV rated to 100 psi (6.9 bar) and 130°F (54°C) maximum operating conditions
- Wetted parts of the RMA-4-TMV: polycarbonate body, Neoprene/Buna-N O-rings, stainless steel metal parts
- RMA-4-TMV body swaps within its 2" scale size for cleaning or a range change, leaving pipework in place
- Weighs 4 oz (113.4 g); the RMA-4-TMV meets RoHS II (EU Directive 2011/65/EU)

- Direct reading scales remove the need for difficult conversions.
- Because the stainless steel backbone absorbs pipe torque, installation damage and costs are reduced.
- Long operational life and a sturdy, non-breakable polycarbonate body.
- Precision injection molding around a precisely tapered pin allows for high reproducibility.
- Improved precision of reading because to unique integrated flow guides that control float movement.
- With the ability to read flow instantly from scale graduations on both sides of the indicating tube, you can save time.
