2.3.3. Flow switches, Contact

Sets, and Water Meters

1.13. Water meters, flow

switches and ‘dry’ contact

sets are connected to input

terminal ‘F’ and a ground

terminal. 5VDC limited by

10KΩ puts 1/2mA through a

closed contact set. Input ‘E’

is reserved for the sample

flow switch function and

cannot be changed.

1.14. Paddlewheel and

Turbine water meters (Hall-

Effect types) are powered by

the 12VDC controller power

supply, and thermally fused

at 100mA.

Connect cabling shields at the

controller ends of the cable only, to any

ground terminal either on the Measure

Card or on the bottom center of the

aluminum frame back plate.
