  • Page 23: Sensor Mounting

    UFM-50 Doppler Flowmeter SENSOR MOUNTING LOCATION The position of the sensor is one of the most important considerations for accurate flow measurement. The same location guidelines apply to Doppler as most other types of flow meters. VERTICAL OR HORIZONTAL PIPE - Vertical pipe runs generally provide evenly distributed flow.
  • Page 24 UFM-50 Doppler Flowmeter SENSOR MOUNTING Prepare an area 2" wide by 4" long (50mm x 100mm) for sensor bonding by removing loose paint, scale and rust. The objective of site preparation is to eliminate any discontinuity between the sensor and the pipe wall, which would prevent acoustical coupling.
  • Page 25 Over time temporary coupling compounds (e.g. Petroleum Gel) may gradually sag away from the sensor resulting in reduced signal strength and finally complete loss of signal. Warm temperatures, moisture and vibration will accelerate this process. Couplants as supplied with the UFM-50 (and available from U-F-M or home improvement stores) is recommended for semi-permanent installations.

  • Page 31: Common Questions And Answers

    UFM-50 Doppler Flowmeter COMMON QUESTIONS AND ANSWERS The pipe vibrates. Will it affect the flow meter? Common vibration frequencies are far lower than the sonic frequencies used by the flowmeter, and will not normally affect accuracy or performance. However, applications where very weak Doppler signal is present (when sensitivity is adjusted to maximum and signal strength is low), accuracy may be affected by pipe vibration, or the flow meter may show readings under no-flow conditions.
  • Page 32 (TV cable type) are not recommended for cable splices. Does the UFM-50 require periodic recalibration? UFM-50 calibration does not drift over time. The solid state sensor has no moving parts to wear and affect calibration. The Doppler flow technique generates an ultrasonic signal proportional to the velocity of flow.
