STEP 2. Orienting the sensor
The sensor will function properly in any orientation if the sensor tubes
remain filled with process fluid. Micro Motion recommends installing D,
DT, and DL sensors as shown in Figure 5.
Flow direction arrow
The sensor has a flow direction arrow (see Figures 1-4) to help you
configure the transmitter for flow direction. Process fluid flowing in the
direction opposite to the flow direction arrow may cause unexpected
transmitter output unless the transmitter is configured appropriately. For
instructions on configuring the transmitter's flow direction parameter,
refer to the transmitter instruction manual.
