The Gas Sampling Unit needs to be level and as close to the area to be monitored as possible, to reduce transport time
to the sensor/transmitter.
•
Refer to Figure 2 for mounting dimensional diagram.
•
Sensor/Transmitters can be located within the Gas Sampling Unit or remotely. Refer to Figures 3,4 and 5
•
Inlet tubing must be compatible with the target gas.
•
Caution should be used to insure that fluids do not enter the inlet tubing.
•
Some types of gases require that the sample gas be removed from the area. This is accomplished with the outlet
port. Figures 7 and 8 show typical use of gas bag and exhaust line from the outlet port.
•
Power is supplied from an external source. Refer to Figures 4 and 5 for wiring diagram. Connect 10 – 30 V DC to
terminal block positions 1 and 3.
•
After installing all the tubing and the sensor/transmitter, verify that there are no leaks in the system. Verification
should be done by plugging the inlet tube. If the system is correct the flow meter reads zero and the flow sensor
activates. If this does not happen, check all fittings and seals.
