For most situations, the meter can be mounted in any orientation. The special cases are:
- High temperature where you should mount the meter so that the transmitter is to the side or below the meter. Transmitters with heat dissipating fins should be mounted sideways so that air can rise up between the fins. For other high temperature applications, mounting the transmitter underneath the meter will reduce the amount of heat which migrates into the transmitter housing.
- If there is possibly entrained bubbles in the fluid or system it is best to place the meter on its side with fluid flowing up through the meter, or upside down so that bubbles do not collect in the measuring chambers.
