Meter Positioning
It is important to install flowmeters so the readings are always accurate. The meters are designed to give a zero
reading should one or more electrodes become exposed. Air bubbles and sediment in the pipe can cause false
readings.
For the best performance, install the flowmeter in pipeline locations where the pipe will be full when there is flow.
Also, rotating the pipe 45° (or one flange hole position) will offset the electrodes enough to avoid air bubble and
sediment locations that typically occur over center within the pipe. The following diagram shows proper and im-
proper installation options.
