Field Testing residential water meters is easy with the unique MUN-1 Utility Service Analyzer. The MARS MUN-1 is a precision microprocessorbased test instrument designed to:

• Verify residential water meter accuracy to within 1/2 of 1% by merely connecting the instrument to the customer’s hose line.
• Check both static and flow pressure at the customer’s residence. If any blockage exists, this data will indicate which side of the meter the problem is on.
• Measure actual flow rate to within 1/10 GPM.
• 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.
