Meter Level – Verometer
This display illustrates the Verometer level in per-
cent. As odorant is pumped out of the Verometer,
the N-300 controller will automatically refill the meter
when the meter level reaches 0%, figure 122.
To manually fill the Verometer, figure 122a, press the *Fill
key and follow the instructions. The following represent There
conditions that will result in a meter alarm indication.
Meter Alarms – Verometer
These are of the displays containing 12 alarm and non-alarm indicators,
figures 123-134, to provide information on Verometer operation.
• Vmtr-Cable, the Verometer cable is not communicat-
ing to the controller, figure 123.
• No Fill, the meter has failed to fill, figure 124.
a. The meter has failed to fill to 100% within six minutes
b. The fill was inhibited due to leakage detection
• Slow Fill, the meter has failed to fill within three minutes,
figure 125.
• Fill Valve, the fill valve has failed to close, figure 126.
• OdorInlet-Cable, inlet fill valve pressure transmitter is
not communicating with the controller, figure 127.
• OdorInlet Lo, the required inlet pressure of odorant is
lower than allowed, figure 128.
• OdorInlet Hi, the required inlet pressure of odorant is
higher than allowed, figure 129.
• XTank-Cable, the expansion tank cable outlet fill valve
pressure transmitter is not communicating with the controller,
figure 130.
• XTank Low, the expansion tank pressure has fallen
below the programmed low-pressure setting, figure 131.
• XTank Hi, the expansion tank pressure has risen above
the programmed high-pressure setting, figure 132.
Meter Indicators, non-alarm
• Over Fill, the meter has been filled in excess of 112%.
a. The Verometer Fill Rate is too fast, in excess of
10 seconds, figure 133.
b. The verometer Fill Valve has failed to close.
• Fill Rate, the meter has filled too fast, in excess of
10 seconds, figure 134.
