Dwyer Instruments RMA

Product Highlights

• Accurate within ±4% of full scale reading
• Scales are brushed aluminum, coated with epoxy and the graduations are on both sides of the indicating tube
• Easy to read design - The direct reading scales eliminate troublesome conversions
• 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
• Construction assures accuracy - All Rate-Master® flowmeter bodies are injection molded of tough, clear, shatter-proof polycarbonate plastic around a precision tapered pin
• The result is accurate and repeatable readings
• The single piece plastic body is mounted to a stainless steel back bone into which pipe thread inserts are welded to absorb piping torque
• For vacuum applications, Model RMA units are available with top mounted valves (specify TMV in the model number)
• Installation is simple - The Rate-Master® flowmeter can be neatly through-panel mounted to keep flow tube centers in the same plane as the panel surface or surface mounted on the panel by means of tapped holes in the backbone
• When through-panel mounted, the bezel automatically positions the instrument at the correct depth in the panel cutout
• Surface mounted units can also be held in place by the piping
• All mounting hardware plus installation and operating instructions are included
• Easy-to-Interchange bodies - Within a given Series Rate-Master® flowmeter bodies can be instantly interchanged
• Simply "unplug" the body from backbone and replace it with another
• O-rings provide a tight seal on inlet and outlet
• Piping remains undisturbed
• Interchangeability is useful where different scale ranges are sometimes required at the same location in the laboratory or plant
• Cleaning is easy - To release the plastic flowmeter body from the stainless steel backbone, just remove four screws
• Pipe thread flow connections remain undisturbed
• Remove the slide cover and the plug ball stop, clean the flow tube with soap and water and reassemble
