The Rate-Master direct reading precision flowmeters from Dwyer Instruments incorporate many unique features at moderate cost.
Ideal for general use, the Rate-Master flowmeters feature direct reading scales designed to eliminate troublesome conversions. The scales are brushed aluminium, coated with epoxy and the graduations are on both sides of the indicating tube. Special integral flow guides stabilize the float throughout the range to keep it from hunting or wandering in the bore. The float is highly visible against a white background.
The bodies of all Rate-Master flowmeters are injection moulded of tough, clear, shatter-proof polycarbonate plastic around a precision tapered pin, resulting in accurate and repeatable readings.
Precision metering valves of brass or stainless steel are available as an optional extra and permit precise flow adjustments.
