Product Overview
The FLOMEC TM Series Water Meter is an economical and robust solution for liquid flow measurement. It features a durable schedule 80 PVC housing and a local display that provides real-time flow rate, accumulated total, and a resettable total. The meter supports three engineering units: Gallons, Liters, and Cubic Feet. It is factory-calibrated and battery-operated for ease of use.
Setup and Installation
The TM10NQ9GMA model features 1-inch Female NPT fittings for straightforward integration into your piping system. Proper installation is crucial for accurate readings and long-term performance.
Installation Steps:
- Prepare the Piping: Ensure the pipe section where the meter will be installed is clean and free of debris. The meter requires a straight run of pipe before and after for optimal accuracy.
- Orient the Meter: Observe the flow direction arrow on the meter body. Install the meter so that the arrow aligns with the direction of liquid flow in your system.
- Connect Fittings: Apply appropriate thread sealant (e.g., PTFE tape or pipe dope) to the 1-inch Male NPT threads of your piping. Carefully thread the meter onto the pipe fittings. Do not overtighten, as this can damage the PVC housing.
- Check for Leaks: Slowly pressurize the system and inspect all connections for leaks. Tighten as necessary.
- Battery Installation: The meter comes with two AAA alkaline batteries pre-installed. If replacement is needed, refer to the Maintenance section.
Operating Instructions

Regular maintenance ensures the longevity and accuracy of your FLOMEC TM Series Water Meter.
Battery Replacement:
The meter operates on two AAA alkaline batteries. When the battery indicator appears on the display, it is time to replace them.
- Ensure the system is depressurized and the meter is accessible.
- Locate the battery compartment on the top of the display unit.
- Carefully remove the screws securing the battery cover.
- Remove the old AAA batteries and insert two new AAA alkaline batteries, observing correct polarity.
- Replace the battery cover and tighten the screws to ensure a watertight seal.
Cleaning:
Periodically clean the exterior of the meter with a damp cloth. Do not use harsh chemicals or abrasive cleaners, as these may damage the housing or display.
