GUIDE LINES FOR USE IN REVERSE OSMOSIS SYSTEMS:
VATS FLOW METERS INSTALLATION GUIDE LINES
For fittings up to 100 NB with flow straighteners:
All flow-straightened fittings require a straight run of 10 D before and 5 D after them
for good results.
Reject flow meter: The disturbances created in the flow/velocity profile are
maximum in this case. It is best recommended to provide an elbow immediately
after the reject control valve followed by the 10 D straight run. In case the outlet
is likely to be opened to atmosphere immediately after the sensor, mount the sensor
in a vertical plane with entry from the bottom.

The unique paddle wheel design of the sensor permits it to be mounted in any plane..i.e.
the unit can be installed in vertical as well as horizontal piping. Insert the blind plug supplied
along with the meter in the fitting and flush the line with water. Depressurize the line, remove
the blind plug and insert the flow sensor gently. Ensure that the sensor O-rings are in place and
slightly greased. Push the sensor in till the threaded cap touches the T fitting. Before tightening
the cap ensure the direction of the sensor is proper. Incase of panel mounted units the arrow on
the sensor should point in the direction of flow. In case of field mounted units the sensor must
be mounted such that the display becomes parallel to the pipe line. Start tightening the cap by
hand. For ensuring the sensor in correct position a male/female locking arrangement has been
provided in the sensor and the fitting respectively. While tightening the sensor cap, by a slight
angular motion, one can get an idea of proper locking properly locked sensor/fitting will not have
any angular motion.

Electronic module: The module basically consists of an LED bar graph of 10 LEDs, which
indicates the % of the output (set), completed. Once the desired output is attained the unit
shows all the ten LEDs ON and the relay inside the unit gets energized for 2 seconds. The
relay output is fed to the auto valve actuator to initiate the regeneration process. Since the
unit is used to initiate regeneration process, the unit must be set for AUTO reset mode i.e.
the batcher would automatically reset after giving a 2 second pulse. The four LEDs below
the bar graph are used in the setting of the batch count.

NOTE:
If the batcher is to be set in an auto-reset mode then all Leds must be ON, where as if only 50% of
LEDs are kept ON then the unit would operate on a MANUAL RESET MODE .i.e. once the desired
quantity of the liquid passes through the meter, the relay would get energised.
Press ENT key to RESET the Relay. In an Auto reset mode the relay would get reset after 2 seconds.
For setting any digit, the SET key is pressed such that the number of LEDs that glow in the bar
graph 0 to 9 correspond to the value of the digit. During normal service the Last LED of the Bar
graph would keep blinking whenever flow takes place. The % completion of the output would get
displayed in the BAR GRAPH.
