Wallace & Tiernan Kynar® Frame Purge Meters are low capacity, variable-area meters which incorporate several improvements in basic meter design. They feature a positive, easily secured tube lock and a plastic frame of Kynar® resin for strength and rigidity, as well as, corrosion resistance in hostile atmospheres.

These purge meters are designed for such service as: liquid-level measurement; orifice or control line purging; leak detection; controlling flow of aggressive fluids - all in the most, highly corrosive atmospheres often found in pulp and paper mills, petrochemical refining plants, and waste treatment plant influent manholes. They are also ideal for air sampling in industrial atmospheres and for proportioning in devices that require mixtures of gases and liquids, such as continuous photographic processes.

Features:

Structurally Strong Frame For strength and rigidity, frames are one piece of solid, molded Kynar®. The frame and “end fittings” are molded in one piece to produce a rigid unit which resists pipe strains and protects tube alignment. Corrosion-Resistant Materials The one-piece frame and “end fittings”, tube retainers, and tube lock are Kynar®. This fluorocarbon plastic frame, unlike acrylic-frame and combination plastic metal- frame meters, resists aggressive process environments and high temperature process fluids. O-rings are Viton®, with Buna N, Kalrez® and EPR (ethylene-propylene rubber) optional. The optional control valve and valve trim are Kynar® and can be located on the inlet or outlet. Positive Tube Lock, Tube Shield A threaded-tube-locking plug, external to the flow, exerts pressure on the tube retainer and locks the tube firmly in place. The tube lock has a screwdriver slot and is accessible from the top of the meter. Tube removal is quick and easy with the meter in the line. O-rings seal the tube at both ends. A clear plastic shield covers the tube. It has tabs which snap into slots in the frame.
