Dwyer MM Mini-Master Flow Meter

Wiratama Mitra Abadi 01 19.47 flow measurement,

Dwyer MM Mini-Master Flow Meters consist of two series of flow meters suitable for both gas and liquid applications with advanced features at a low cost. The Series MMA is a 2" (51 mm) scale flow meter that is user-configurable with or without non-removable top or bottom front-mounted metering valves.

It is constructed from transparent nylon material providing high chemical resistance and is easily disassembled via the provided key for cleaning or reconfiguration. The Series MMF is a 1-1/2" (38 mm) scale compact flowmeter ideal for measuring small volume air. It features bezel-type mounting that can be quickly installed from the front of the instrument panel.
