2.8 External Devices
You can connect the sampler to an external
instrument (Figure 2-9) for a variety of reasons.
Typical reasons include:
• Receiving flow pulses from a flow meter
device for variable time.
Figure 2-9 External device connections are
located on the upper right side of the sampler
• Receiving an enable pin signal to enable
sampler operation once site conditions
warrant sample collection.
• Receiving a linear 4-20 mA analog or
pulse representation of the flow rate for
variable time
.
• Sending alarm signals when sampling
events occur.
