Flow Meter Calibration

The Sample Sentry II system has a stated flow accuracy of ± 3% of full scale which

correlates to ± 102cc. Under normal operation of the system this value is fine; however, if

additional accuracy is required it possible to generate a multiple point correlation table to

normalize each system to a specific sample point. The default values for the screen are:

Setpoint 1: 0 = 0

Setpoint 10: 3393 = 3393

If you want to make adjustments to this table please consult Sentry Equipment for a

detailed procedure or field service assistance.

Installation

This instrument should be installed by qualified technical personnel to ensure adherence to all

applicable electrical codes .
To ensure the protection provided by this equipment is not impaired, this equipment must not

be installed or used in any manner other than that which is specified in this manual .

Unpacking

After carefully removing the Sample Sentry II from its shipping carton, inspect it for any

damage. Report damages to the shipper immediately.

Mounting

Bolt the units to the wall using four 3/8" bolts. To simplify installation, first mount the

unistrut to the wall and then mount the single line to the unistrut.
