Features: For high integrity of high pressure duty Suitable for flush panel mounting Scaled for specific process conditions PLATON METAL TUBE PURGE FLOWMETER—TYPES API, APT, APV Armoured Purgemeters are direct reading flowmeters for liquid or gas measurement on small lines. Using a stainless steel tapered tube to create a variable area flowmeter, the magnetically coupled pointer shows flowrate on an external scale. Armoured purgemeters are chosen where the higher integrity offered by a metal flow tube is important, or where conventional glass flow tubes are not allowed in the process. Ideal for flow monitoring in purging, mixing or sampling systems, the meters are available with inline (API) or rear facing (APT) screwed connections. For fine flow rate adjustment, the APV model has an integral multi-turn needle valve. Scales are individually produced to show the actual fluid flow for the process fluids and conditions relevant. The units are suitable for flush mounting in a control panel, using a simple mounting kit.

VDE/VDI 3513 Class 4 standard ± 0.5% FSD 20°C to +150°C 150 bar max (non valved models API, APT) 40 bar max (model APV with valve) 1/4" NPT female OPERATING PRINCIPLE The VA meter principle used in the Armoured Purgemeter measures the position of a float in a preci- sion machined tapered tube.The float rises with the fluid flow up the taper until the upthrust balances the float weight. A magnet, sealed within the float casing, drives the external pointer over a full 90°C rotation against a scale printed in actual process flow units. The meter housing secures the different styles of end block in place, which provide the process connections: between these the flow tube is O-ring sealed onto the end block. Standard units require no electrical connection. API APV APT Special versions are available with improved accuracy or built to withstand high temperatures or pressures, or with alternative process connections or from alternative materials.
