Initial installation occurs at the factory, where the sensor is installed in a flow meter. The user’s manual shows the sensor in
place in the flow meter. The manual includes a ‘Meter Disassembly and Repair’ section. See part A: Pulser O-ring or Pulser.
There are no replaceable parts in the sensor assembly itself. The flow meter must be drained of fluid and depressurized
before sensor replacement. The replacement sensor must be installed exactly as the original. Opening of any associated
devices to disconnect and reconnect the sensor cable must be done according to safety standards applicable to the hazard-
ous area. The cable attached to the sensor needs to be suitably protected and terminated in an ATEX approved terminal
assembly, that provides the same level of protection as the sensor itself.

The standard meter pulser is a Hall Effect device, which may have one or two output signals. Some reed switch pulsers are
available for battery powered registers. A PIA-300 pulse isolator/amplifier may be required for longer cable lengths.

The pull-up resistor provides the necessary voltage and current levels to guarantee a logic-1 level,
whenever the output transistor is in the ‘off’ state. Most sensors have internal 10K ohm pull-up resis-
tors. Some pulse receivers have pull-up resistors. Refer to the receiver’s manual.

If connected incorrectly,
The pulser will be
damaged beyond repair.
