Description

Series RMVII Rate-Master® Dial-Type Flowmeters

For Panel Mounting, Three Ranges to 10 GPM Water, High Pressure Limits

The Series RMVII Rate-Master® Flowmeters consists of a machined brass meter body which 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.

 

Product Applications

• 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

 

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 flowmeters, yields long operation life
