Metal Tube Purge Flowmeter – Overview Ideal for liquid or gas flow monitoring on small lines in purging, mixing or sampling systems. It uses a stainless steel tapered tube to create a variable area flowmeter. The magnetically coupled pointer shows flow rate on an external scale. Metal Tube Purge Flowmeters are used where the higher integrity offered by a metal flow tube is important, or where conventional glass flow tubes are not allowed in the process. 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. Standard units require no electrical connection.
