Platon Plastic VA Flowmeter – Overview Type PG and PGU flowmeters are low-cost variable area flowmeters for liquids or gases, in pipe sizes 1/2” or 1”.The shatterproof TPX moulded tapered indicator tube has a 100mm linear flow scale with a 10:1 flow range. The stainless steel or Dural float rises with the flow to an equilibrium position. The flow rate is then read from the top of the float. Scales are etched directly onto the plastic flow tube ensuring high float visibility so that it can be easily read at a distance. They are available with air or water scales etched into the flow tube. Glass tubes are also available, which can be supplied with custom scales to suit process conditions, in the PGU housing. TPX plastic has excellent resistance to most chemicals and gases. It is also non-toxic and boilable. Type PG is a lightweight, open construction ideal for surface mounting or portable use. For alternative process liquids or conditions, external laminated scales are provided and positioned in front of the flow tube. Type PGU has a rigid diecast housing with a Perspex window, giving it complete protection from random damage. This flowmeter is suitable for unsupported mounting in process pipework.
