Orientation
Positive displacement gear flow meters can be installed either a horizontal or
vertical (flow up) orientation. 2-3 psi of backpressure is required to assure
the meter is always full of fluid. No straight run pipe is required upstream or
downstream of the meter.
Flow Direction
Flow direction is marked with an arrow on the flow meter. See Figure 2.
