PURGE METER (LOW-FLOW ROTAMETERS) |
| Measure low flows of gas, air, water with accuracy using this type of flowtube. This is ideal for laboratory or instrumentation applications. Mounting can be panel or by optional tripoid base. Available in complete acrylic body or stainless steel body with glass metering tube. Dependable flow control is provided by needle valve located at inlet front of frame. Centre line dimensions standard for back panel mounting are 65mm, 150mm and 200mm |
FULL - VIEW ROTAMETERS (GLASS TUBE TYPE FOR GENERAL INDUSTRIAL SERVICE) |
| These glass tube variable area rotameters are designed to provide visual indication of flow of wide
range of transparent to semi-transparent liquids and gases. They are of robust construction with dowelled side plates, interchangable glass metering tubes and floats and wide-view windows at front and rear. Flow range can be readily changed by detachable scales. |
BY- PASS ROTAMETERS (ORIFICE PLATE WITH CARRIER RING AND BY-PASS ROTAMETER) |
| By-pass rotameters are suitable for economical measurement of flow in larger pipelines generally 2" NB to 14" NB. The 1/ construction is simple and reliable consisting of orifice plate with carrier ring and a shunt rotameter. The flow rate through the , rotameter is proportional to the pressure drop across the orifice plate created by the main flow and is calibrated accordingly.
During installation care should be taken to ensure laminar flow in the pipe section. Orifice plate dimensions are based on ISA / ISO / BS standards. |
Metal Tube Rotameters |
Armoured metal tube rotameters are recommended for liquids or gases where process or
operating conditions make all-metal construction desirable. This type of rotameter is also useful for metering opaque fluids. 'The meter is manufactured in various materials of construction and with 150,300 or 600 # flange connections. In our model RMC - 100 an extension with magnetic lenier indicating scale is bolted to the meter to indicate the float position. In another modification model RMC - 200 a dial type of indicator is provided. |
