Feature
- 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.
- Precision metering valves of brass or stainless steel (specify BV or SSV on order) are available as an optional extra and permit precise flow adjustments.
- 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.
