- High dynamic flow measur ement Applicable for liquid flow measur ement up to 600 ml/min (36 l/h) No moving par ts in medium P rotection class IP65 Fieldbus optional Type 8709 is an instrument for liquid flow measurement in process technolo- gy. The actual value supplied by the sensor is transmitted through the digital electronics and over a standard signal output or a fi eld bus interface. In the device two calibration curves can be stored, which the user is able to switch between. Product variants described in the data sheet may differ from the product presentation and description.

- P roduct operation 5.1. Measuring principle
- The sensor measur es the flow by means of differential pressure. An orifice in the main channel causes pressure loss at liquid flow which is measured by the differential pressure sensor. The sensor feedbacks a precise and temperature compensated signal out of which the electronics calculates the corresponding flow. T o avoid a blockage of the aperture by contaminated mediums an upstream filter is recommended. p1 p2 5 10 15bar 0 5 10 15bar

Recommendation r egarding product selection Note: The decisive factors for the perfect functioning of an LFM within the application are the fluid compatibility, the pressure range and the correct choice of the flow meter range. The pressure loss over the LFM averages in typical applications approx. 500 mbar, with up to 2 barg inlet pressure. The specification of the inlet pressure, p1max, which can be expected is necessary for the selection of the suitable differential pressure sensor. Please use the „Product Enquiry Form“ at the end of this document to indicate the pressures directly before and after the LFM. If these are unknown or not accessible to a measurement, estimates are to be made by taking into account the approximate pressure drops over the flow resistors before and after the LFM, respectively, at a flow rate of Q Nom. In addition, please quote the maximum in- let pressure p1 max. to be encountered. This data is needed to make sure the actuator is able to provide a close-tight function within all the specified modes of operation. 6.3.
