PWE paddle-wheel flow meter Product Summary PWE paddle-wheel flowmeter for liquid flow measurement. This unit can be con gured on-site directly through the built-in user interface. This is often a regular maintenance task for instrument technicians: using a hand pump to inject light-weight “turbine oil” into the bearing assemblies of turbine flow meters used in gas service. The 2537 Paddlewheel Flowmeter Series o er low ow, low power and high resolution with various output options such as a Volumetric Pulse, Pulse Divider, Flow Switch, Digital (S3L), or 4 to 20 mA. diesel fuel), but in applications such as natural gas flow where the fluid provides no lubrication to the turbine bearings, external lubrication must be supplied. The problem is not as severe in applications where the process fluid is naturally lubricating (e.g. Frictionless motion of the turbine wheel is essential for accurate flow measurement, which is a daunting design goal for the flow meter manufacturing engineers. In processes where the fluid flow happens to pulse for reasons other than the control system opening and shutting automatic valves, this problem is more severe.Īnother problem common to all turbine flow meters is lubrication of the turbine bearings. This way, when the shutoff valve closes and fluid flow immediately halts, any coasting of the turbine wheel will be irrelevant. This problem may be minimized by configuring the measurement system to ignore turbine flow meter signals any time the automatic shutoff valve reaches the “shut” position. This is more often a problem in batch processes than continuous processes, where the fluid flow is regularly turned on and shut off. Can only be used with liquids, ideally low viscous liquids.A problem common to all turbine flow meters is that of the turbine “coasting” when the fluid flow suddenly stops.The pipe work must be full at all times.Some applications will require straight pipework before and after the flow meter.Paddle wheel flow meters also have some limitations which are listed below: Economical price with a low cost of ownership.These meters measure the flow rate of liquids and operate based on the principle of a rotating paddlewheel placed in the path of a fluid. KF510 Paddle Wheel Flow Meter Union Type. KF510 Paddle Wheel Flow Meter Flange Type. KF510 Paddle Wheel Flow Meter Wafer Type. Easy installation, operation and maintenance Paddlewheel Flow Meters are important devices used in a variety of industrial, commercial, and laboratory applications. Lead Time: 4 weeks Categories: Paddle Type Flow Meters / Switch, Flowmeter.Paddle wheel flow meters have many advantages which include: The difference is that a paddle wheel flow meter is not directly in all of the flow path, whereas with a turbine flow meter the turbine blades will cover the majority of the cross sectional flow path. The speed at which the wheel rotates is detected and this is converted into a volumetric flow rate. Our paddle wheel flow meters are popular due to their wide range in flowrates, negligible head-loss, and good. They are universally accepted as an accurate means of measuring water flow electronically. The wheel is fixed and the faster the flow rate of the fluid, the faster the paddle wheel spins. These flow meters are designed for use in industrial fields, including irrigation, aquaculture, aquariums, paper mills, and swimming pools. The operating principle is similar to that of a turbine flow meter, whereby flow within the pipework allows a wheel with paddle to rotate freely with the flow of the fluid. The chemical flow sensors can be installed into pipe sizes ½ 24 using our line of comprehensive custom fittings. The TIW insertion paddle wheel flow meter is available in PVC, PP and PVDF. Paddle wheel flow meters can operate as both in-line flow meters or insertion style flow meters. The TIW liquid flow meter, is industry’s longest lasting paddle wheel flow meter and comes with a lifetime warranty on the paddle wheel assembly.
