Dwyer MMA-31 | Mini-Master Flowmeter | 1-16 GPH Water
The Dwyer MMA-31 Mini-Master flowmeter reads 1 to 16 GPH of water on a 2" (51 mm) scale. The MMA-31 is a user-configurable Series MMA unit with a non-removable metering valve mounted top or bottom on the front, and its translucent nylon body can be taken apart for cleaning or reconfiguration using the supplied key.
- Measures water from 1 to 16 GPH
- ±4% full-scale accuracy over the 1-16 GPH water span
- 1-16 GPH water model built in translucent Nylon 12 with Buna-N O-rings
- Rated to 100 psi (6.9 bar) with compression fitting, 50 psi (3.4 bar) with tubing clamp, 130°F (54°C), for the 1-16 GPH water scale
- 5/16" OD tubing connection with spring clamp provided on the MMA-31
