polycarbonate flowmeter

series rm rate-master® polycarbonate flowmeter

2", 5" or 10" scale, interchangeable bodies

the series rm rate-master® flowmeters are a line of general use, direct reading precision flowmeters suitable for both gas and liquid applications. This series consists of 2" (51 mm), 5" (127 mm) and 10" (254 mm) scales that can be panel or surface mounted with optional precision metering valves. Within a given series, the rate-master® flowmeter bodies can be instantly interchanged, allowing the piping to remain undisturbed, interchangeability of the ranges, and easy cleaning.

product applications

• medical equipment
• air samplers
• gas analyzers
• pollution monitors
• chemical injectors
• cabinet purging

specifications

• service:compatible gases and liquids.
• wetted materials:body: polycarbonate; o-ring: neoprene and buna-n; metal parts: ss (except for optional brass valve); float: ss, black glass, aluminum, k monel, tungsten carbide depending on range.
• temperature limit:130°f (54°c).
• pressure limit:100 psi (6.9 bar).
• accuracy:rma: 4%; rmb: 3%; rmc: 2% of fs.
• process connection:rma: 1/8"; rmb: 1/4"; rmc: 1/2" female npt.
• weight:rma: 4 oz (113.4 g); rmb: 13 oz (368.5 g); rmc: 39 oz (1105.6 g).
• agency approvals:meets the technical requirements of eu directive 2011/65/eu (rohs ii).
• caution:dwyer® rate-master® flowmeters are designed to provide satisfactory long term service when used with air, water, or other compatible media. Refer to factory for information on questionable gases or liquids. Caustic solutions, anti-freeze (ethylene glycol) and aromatic solvents should definitely not be used.

features

• direct reading scales eliminate the need for troublesome conversions
• stainless steel backbone absorbs piping torque reducing installation damage and cost
• shatter-proof polycarbonate allows for long operation life
• precision injection molding around a precision tapered pin enables high repeatability
• increased reading accuracy with special integral flow guides that stabilize float movement
• scale graduations on both side of the indicating tube allow for instantaneous flow reading saving time

options

• top mounted metering valves - same precision construction for vacuum applications rma models only.
• adjustable pointer flags - red lined pointer flags provide quick visual reference to a required flow level. Of clear plastic, they snap into place inside bezel and slide to desired level.
• specials - special ranges, scales, mounting arrangements, etc., are available on special order, or in oem quantities.
