** Each sensor is calibrated with specific meter. Hence use the
sensor & meter as a single set.
GETTING AQUAINTED WITH THE METER:
This meter is user friendly & easy to understand. Its operation
will be clear when we go through all the parts of the meter.
It is the main part of flow meter. It consists of a
turbine having magnets on its periphery. As the turbine rotates
pulses are generated and sensed. These pulses are proportional to
the flow through pipe.
This is the unit that processes the information received
from sensor and displays actual flow in the line. this unit
also controls the flow by transmitting signals to dosing pumps,
hooters, valves etc through inbuilt relays.

1) While installing the sensor in line follow the arrow direction on the
sensor body.
2) Sensor will be ideally located in horizontal line with minimum
straight run as mentioned above.
3) Ensure upstream & downstream of 10 inches & 20 inches on
either side for 1” & 2” line size respectively.
4) It is recommended not to loosen or tighten NUTS of the
sensor while fitting on line (use extra union connectors on both
ends).

ON SITE CALIBRATION OF METER:
Each flow meter normally comes duly calibrated along
with the corresponding sensor (for a given line size). In case re -
calibration is required at site,the previously programmed channel
constant can be increase/decreased in proportion to the difference
n the reading between the actual flow and the displayed reading.
Follow the instructions given below.

PROGRAMMING FLOW MONITOR:
Aster Flow Monitor is user friendly and can be operated in
following different modes as:
Batcher Mode/Totaliser Mode
Flow Comparator Mode
Rate switch mode
Pulsar mode
[To change the settings i.e . (operating the meter in a mode
other than Totaliser) contact nearest dealer.]

BATCHER MODE:
In this mode the relay is programmed to operate after a
fixed quantity of water passes through the sensor. When the power
to the unit is switched ON, it displays
ASTER
And then FR1: 00000.0 Lit /hr
Press scroll key to toggle between Total O/P T1 : 00000.0 Lit &
Batch Qty B1 : 00000.0 Lit
The unit will count down the batch volume till value
becomes zero after which relay will get energized.Relay could
Operate in the following modes in case of a batcher.
(1) Auto reset: In this mode relay will give a 2 sec pulse and
will get reset aNd meter will start counting down the next
batch.
(2) Manual Reset:

Once programmed quantity of water has
passed through the sensor,relay will get energized with
“BATCH OVER “indication on the display.Relay can be
reset by pressing ACK. key
(3) Two Relay Operation: When 80% of the water batch
quantity passes through sensor ,the first relay gets
energized .This relay can be reset by pressing the ACK. key
and second relay will get energized with “BATCH OVER“
indication on display after programmed quantity of water
passes. Relay can be reset by pressing ACK. key

FLOW COMPARATOR MODE:
This mode is ideal for Reverse Osmosis systems. Here the
meter is supplied with 2 sensors (one for permeate line and the
other for reject or feed line). The meter displays both the flow
rates and also calculates the % RECOVERY. One could set the relay
at a particular recovery % and relay would get energized
whenever the system recovery crosses the set point.

Aster Tcnologies
eh
NOTE:Second sensor is normally supplied for reject flow sensing.
This can however be assigned as the inlet sensor. To change the
factory settings, contact nearest dealer or supplier.
9
Recovery can be calculated by the formula:
Permeate flow Rate (PR)
% Recovery =
Permeate flow rate(PR) + Reject flow rate (RR)
The relay will get energized, if actual recovery exceeds the set
value.
