PIN DESIGNATIONS
Keyway notch at 12 o'clock
2 o’clock socket location is ground
6 o’clock socket location is signal
10 o’clock socket location is power
VOLTAGE READINGS
2 o’clock socket to 6 o’clock socket = +5 VDC
2 o’clock socket to 10 o’clock socket = +5 VDC
TEST PROCEDURE
- Disconnect flow meter cable from the flow sensor and hold flow sensor cable so that the keyway is pointing to the 12 o’clock position.
- Using bent paperclip, insert into sockets at 2 and 6 o’clock and touch sides; wiggle the paperclip ends around for a few seconds.
- If tank volume displayed on terminal has decreased, this shows the cabling and connections are good; likely that the flow meter has gone bad.
