Series IDP — plastic flow indicator

• Direct reading • All plastic • Materials: PVC or polysulfone • Scales: water: 50...60,000 l/h • Options: adjustable contacts, 4-20 mA transmitter strip For continuous flow measurement on air and on neutral, acidic and alkaline liquids. The IDP works on the variable-area principle: the flow of fluid lifts a float in a tapered tube, increasing the flow area. The float rises up the tube in proportion to the flow rate. As standard, these flowmeters come with scales in l/h for water at 20 °C. Ranges are also available for air (1 to 2 bar absolute, in Nm³/h), HCl at 30 and 33%, and NaOH at 30% and 50%. See technical data sheet 730-06. With the magnetic versions, the Z60 transmitter strip converts the float position into a 4-20 mA signal. See technical data sheet 730-07. Mounting precautions: Variable-area flowmeters must be installed vertically with upward flow. A straight run of 10 x DN upstream and 5 x DN downstream is recommended (minimum according to NF X 10-102).
