  • Page 5: General Information

    502 010 07 1 General information Introduction The PD 340 Flow Transmitter is a precision meter for the volumetric measurement of liquids that are electrically conducting. The rugged construction of the transmitter makes it suitable for installations where solid par- ticulates make up part of the liquid for measurement.

  • Page 6: Construction

    502 010 07 Construction The PD 340 Flow Transmitter consists of three parts: The meterhead, the electronic module, and the terminal box. The electronic module and the terminal box are the same for all sizes of transmitter. The Meterhead consists of a stainless metering pipe with clamp connections. Two magnet coils are mounted external to the metering pipe.

  • Page 8: Operating Principles

    (see details in the next chapter, Reducing the influence of varying flow profiles). Practical tests with the PD 340 confirm that it is not necessary to recalibrate the meter when changing product, such as from water to milk. This would normally be necessary when using magnetic flowmeters that have traditional round measuring chambers.

  • Page 9: Reducing The Influence Of Varying Flow Profiles

    Measures over The average measurement is achieved in a PD 340 by using a the entire cross square measurement chamber, where each of the two electrodes are section of the designed to measure across the complete cross section of flow.

  • Page 10: Linearizing Function

    During the flow calibration at the factory, the linearizing curve is calculated and downloaded to the electronic module. For this reason, all new PD 340 Flow Transmitters will hold the data needed by the linearizing function, when they are delivered as complete meters, i.e. meter- head and electronic module.

    502 010 07 3 Display Various options are available for displaying information from the PD 340 Flow Transmitter. The Flow Transmitter may be controlled and supervised via the P-NET interface (requires the ex- tended version), and all data may then be accessed. Another solution is to connect a local PD 210 display unit to the Flow Transmitter.

Some variables are stored in both non-volatile memory and in volatile memory. The state of the module's Program enable switch determines whether the contents are changed in both types of memory or only in the volatile type.
