Variable-area flow meters have generally been specified in process applications where cost is a major consideration and high accuracy is not always required. However, the nature of modern processes with their demands for low maintenance and reduced downtime to optimise production means that another more accurate flow meter is required. Burkert is meeting this requirement, providing a modern competitively priced alternative to conventional rotameters with its Type 8032 inline - paddlewheel flow indicator/transmitter/switch.
Industry approved, the Type 8032 integrates the functions of monitoring, transmitting and on/off control into one intelligent device with the added benefit of easy-to-read digital indication. In addition, the Type 8032 also offers users the time saving feature of automatic calibration, via a teach-in function, as well as selectable outputs: transistor, relay or 4-20mA.
The simplicity of the paddlewheel design means that the 8032 can be mounted vertically or horizontally, to simplify piping and installation generally. Moreover, the choice of materials for wetted parts of the flowmeter, including brass, stainless steel, PVC, PP or PVDF / FKM (EPDM option), and PVDF /ceramics for the paddlewheel, allow the unit to be used with a wider range of fluids.
Complementing its flexibility in operation, the Type 8032 is a low maintenance unit that reduces process downtime. The unit is designed so that no interruption of flow is required for maintenance, or for future product updates. The fact that the paddlewheel is the only replaceable part in the Type 8032 also adds to its low maintenance credentials, saving downtime and inventory costs for the user.
The Type 8032 has a wide measuring range from 0.3m/s to 10m/s with linearity of ±0.5% of full scale (10m/s) and repeatability at ≤ 0.4% of reading. The unit can handle liquids –including clear, coloured, neutral and aggressive types – up to 300 cSt. maximum, with negligible pressure drops.
With its flexible outputs and facility for remote operation, the Type 8032 offers multiple interconnection possibilities with complementary process control products from Burkert. These include solenoid valves, ELEMENT control valve systems, Type 8792 positioners, Type 8644 valves islands and flow sensors.
