step should be cemented with an approach angle of not more than 15 degrees. The recess
must extend over the full width of the bed of the channel to accommodate the Magnetic
Enhancement Plates.
Note: CM2/8” ChannelMag sensors are normally supplied with ramps.
ChannelMag PM Series sensors are used for full pipe flow measurement from 20”
- 120” (500 - 3000 mm) diameter. For 20” - 47” (500 - 1195 mm) diameter a single sensor or
double sensor is used, dependant on the number of straight lengths of pipe available. For 48” - 120”
(1200 - 3000 mm) diameters either 2 sensors or 4 sensors are used, again dependant on available
straight pipe lengths.
The sensor(s) are attached to a stainless steel retention band designed for a specific pipe internal
diameter. The retention band is equipped with an expander mechanism, which opens out against the
pipe internal diameter to secure the sensors. In this way the pipe wall does not require holes or
fixtures and is ideal for concrete tunnels.
