Installing a MACE Doppler ultrasonic insertion sensor
WARNING: DO NOT cut the sensor cable. Re-termination of the sensor is highly
specialised and MUST be carried out at a MACE technical facility.
WARNING: Don’t mount the sensor at the top of the pipe as air pockets could give
unreliable readings. Don’t mount the sensor at the bottom of the pipe as silt build-up
can cover the sensor. Only mount the sensor between 2 and 5 o’clock as shown
below. MACE recommends mounting the sensor facing upstream wherever possible.
1. Using a 2” coring bit (hole saw) appropriate for the pipe material (eg. in a concrete pipe MACE
recommends the use of a diamond tipped bit), carefully core the pipe so that a clean cut is obtained.
NOTE: The hole should ALWAYS be only just bigger than the sensor head.
2. Measure and record the pipe wall thickness.
3. Attach a male 2” BSP or NPT nipple to the pipe DIRECTLY CENTRED OVER THE HOLE in a
manner suitable for the pipe material. This fitting must:
• Be at right angles to the flow
• Provide for a clean join inside the pipe (no burring etc)
• Be watertight
