When it comes to flow...we’re instrumental.

7750 series 4-20 ma transMiter

To convert the measured flow into a 4-20 mAdc signal, an angle of
rotation transmitter is mounted to the indicator. This device is fac-

tory calibrated to ensure accuracy and should only be adjusted by
King Instrument Company.

All 7710 Series flowmeters may be fitted with one or two inductive slot sensors.

Inductive slot sensors are 2-wire, DC, low current devices and are designed to

be used with a remote barrier / switch isolator capable of powering the sensor

and providing the desired switching option(s). Barrier / switch isolators are

available with 220VAC, 110VAC or 24VDC supply voltage requirements, contain

single pole double throw (SPDT) relays, and are DIN rail mountable. (Only

24VDC units are actually powered by the rail.) See barrier / switch isolator

specifications for electrical connections and further details.

SETTING ALARM TRIGGER POINTS:

1) Remove the eight screws securing the SHIELD.

2) Remove the SHIELD.

3) Carefully loosen the ALARM NUT. (Loosen just enough to rotate the ALARM

SENSOR BRACKET).

4) Carefully rotate the ALARM SENSOR BRACKET to the desired alarm set

point. If the meter has DUAL ALARMS, set the LOW ALARM set point and then

the HIGH ALARM set point.

5) Tighten the ALARM NUT.
6) Replace the SHIELD and secure with the eight screws.
