Dwyer RMVII Series Rate-Master® Dial-Type Flow Meters

Wiratama Mitra Abadi 01 01.54 flow measurement,

Dwyer RMVII Series Rate-Master® Flow Meters consists of a machined brass meter body that is ideally suited for water flows with ±5% of full-scale accuracy. Body design fits standard 4-1/2" mounting hole layouts per ANSI B40.1. Inlet and outlet threads are standard 3/4" female NPT.

Dwyer offers different types of Dial Flow meters for various applications. Flow meters measure water, oil, gas or airflow rates. Applications include calculating required fill or drain times for tanks, water towers, backflow prvention, heat exchangers, and oil & gas equipment.

Dwyer RMVII Series Features

Unique construction fully isolates flowing media from gage front for leak-proof operation at pressures up to 3000 psig (206.7 bar)
Target-type design combined with a damage resistant magnetic linkage, drive a pointer over easy-to-read litho scale
Shatter proof construction, unlike glass tube variable area flow meters, yields long operation life

Application

Monitor coolant flow through ingot heaters, high-amp switchgear, resistance welders, heat exchangers, compressors, scrubbers
Monitor water consumption to different processes and operations for more efficient operations
Calculate required fill or drain times for tanks, water towers
