The following should be taken into consideration:
(1) Easy access to the unit for checking and maintenance work.
(2) Near to the detector and the converter
(3) No corrosive gas.
(4) An ambient temperature of not more than 55 C and little change of temperature.
(5) No vibration.
(6) Little exposure to rays of the sun or rain.
The Automatic Calibration Unit can be mounted either on a pipe (nominal JIS 50A ) or
on a wall. It should be positioned vertically so that the flowmeter works correctly.
<Pipe Mounting>
(1) Prepare a vertical pipe of sufficient strength (nominal JIS 50A: O.D. 60.5 mm) for
mounting of Automatic Calibration Unit. (The unit weights approximately 3.5 kg.)
(2) Mount the Automatic Calibration Unit on the pipe by tightening the nuts with the U-
bolt so that the metal fitting is firmly attached to the pipe.
