• Only NIST Traceable Portable Tester
• .1% Repeatable Accuracy
• 10-Point Linearization
• Illuminated Display
• Resolves Customer Complaints on the Spot
• 1-Year Limited Warranty

Hardware: Consists of a NIST traceable 3” turbine meter, NIST traceable 5/8” turbine meter, 3” gate valve, 3/4” ball valve and a pressure gauge. Inlet and outlet are equipped with brass National Standard Fire Hose swivel couplings.

Installation: Directly to 2 1/2” National Standard Fire Hose coupling threads. The meter must be at a full flow of liquid and 3 feet of straight inlet hose for proper accuracy. For safety reasons, the MUN-4 must be rigidly secured prior to starting test.

Rotor: Lightweight hydraulically balanced Stainless Steel rotating on cyro ball bearings. The precision rotor is designed for extreme accuracy at low flow rates and accurately register across the operating range of the meter. The rotor, which is the only moving part in the meter, electronically drives the sensor output, which is proportional to the flow through the meter.

Totalizer: Explosion proof aluminum, FM Approved, NEMA 4 enclosure. Multi-function LCD display with green LED backlight. 10-point inearization for maximum accuracy at any flow rate without the need for a correction card. On-the-fly test mode allows for greater testing accuracy at target flow rates. Up to 8-year battery life using a Lithium battery.

Available with hose and fitting accessory kit.
