Direction of Horizontal Flow

Static back pressure / min. 0.1 bar (1.5 psi)

Horizontal sensor mounting is recommended for air/gas processes.

A shut-off valve should be installed to facilitate the zero-point adjustment of
the sensor. To avoid elimination of the air form the process, a back pressure

of a minimum of 15. to 3 psi is recommended.

The arrow on the sensor indicates the direction of positive flow (the meter is
able to measure flow in both directions).

The liquid should flow in the direction of the arrow (on the sensor) to avoid

partial emptying of the sensor, especially with low flow.

There should be a check or solenoid valve that closes when the flow is zero

so that the liquid does not flow back and causes partial emptying of the sensor.

The CMF-A is most efficient for gas applications when it is mounted as shown. The
CMF-A is most efficient for liquid applications when it is mounted as shown.

With vertical mounting the orientation of the terminal box is not important, rotation,

however, is not allowed to exceed the stated angles of the sensor.

Mounting of the Pressure Switch

mportant

Read the following information before removing the nipple from the sensor

enclosure.
Avoid getting humidity, liquid or particles into the sensor. It may damage the

meter. Following this procedure is recommended.

1. Leave the sensor in a dry and clean place to acclimate until it obtains

ambient temperature, best at approximately 70°F (20

°C).

2. Be careful when removing the nipple and mounting the pressure switch.

3. Check the pressure switch has been correctly mounted and tightened so

the sealing ring fits tightly. Always replace old sealing rings with new ones

after each disassembly.

Connecting the Pipe

Important
When connecting/disconnecting the pipe, the cable has to be mechanically

connected in order to prevent liquid from penetrating into the sensor. The

sensor is only IP 65 (dust and splash proof) when the plug is mounted.
