Digital LCD Flowmeter for Water Filtration

The IDENTER Digital LCD Flowmeter is a monitoring accessory for water filtration systems, dispensers, coolers, coffee machines and beer brewing setups. It installs inline with a 3/8 inch NPT female connection and includes quick fittings for both 1/4 inch and 3/8 inch OD tubing. The unit displays remaining capacity and elapsed time on an LCD screen and provides audible alerts when the programmed volume is reached or battery power runs low. It is powered by two included AAA alkaline batteries.

Flow Rate Limits and Measurement Accuracy

The sensor operates within a flow range of 0.55 to 3.72 gallons per minute, or 2.1 to 14.1 litres per minute. Readings carry a measuring accuracy of ±10 percent. The device functions at water temperatures from 32 to 104 degrees Fahrenheit (0 to 40 degrees Celsius). It is not suited for flows below the stated minimum or for liquids outside the specified temperature window.

Capacity Tracking and Battery Life

Users can program a countdown volume between 100 and 9900 gallons or litres. The display tracks the remaining amount and elapsed time until the alarm triggers. Two AAA alkaline batteries supply 3 DC volts at 1.0 milliampere during operation and 0.015 milliampere in sleep mode, lasting more than two years. The meter weighs 140 grams (5.38 ounces). It does not filter water or control flow mechanically.

Questions about this item

Should I pick the 1/4" OD or 3/8" OD quick fittings for my 3/8" NPT port?

Both sizes are included — two of each — so you can match the tubing you already have without buying extra adapters.

What does the 3.72 GPM rating mean when the meter is installed in my filter line?

It is the maximum continuous flow the sensor can measure; actual flow will be limited by your pump and filter, and the meter reads accurately from 0.55 GPM up to that ceiling.

How does the 3/8" NPT female connection limit what I can attach?

It accepts any 3/8" NPT male thread; the two supplied quick fittings (1/4" OD and 3/8" OD) cover the most common tubing sizes for filters, dispensers and brewing gear.
