The MUN-1 is a precision microprocessor- based test
instrument designed to:
- Verify residential water meter accuracy to within .5% by merely
connecting the instrument to the customer's hose line.
- Check both static and flow pressure at the customer's residence.
- Measure actual flow rate to within 1/10 GPM. If any blockage
exists, this data will indicate which side of the meter the problem
is on.
- Serve as a rate of flow indicator, line pressure gauge and comparison
tester for small meter shops not equipped with a full test bench
and calibrated tanks.

In operation, pulse signals generated by the turbine
flow sensors are magnetically transmitted to the microprocessor, then
computed into U.S. Gallons, Cubic Feet, or Liters and shown on an
easily read LCD display. Power is provided by two extra long life
(10 years of normal service) lithium power cells which automatically
power down when the MUN-1 is not in use.
Although the MUN-1 was designed primarily as a field test instrument
for resolving customer complaints, a number of water utilities are
using the MUN-1 to test all of their meters in service as the most
efficient and economical means of checking accuracies and recouping
lost revenue from faulty meters.
