Professional-grade positive displacement flow meter with the largest display in its class. Simple menu-driven operation, all-in-one calibration, and Viton seals make the ZFM-V ready for DEF, chemical transfer, batch mixing, and general fluid management.
The Remco ZFM-V is a nutating disk, positive displacement electronic flow meter built for operators who need accurate, repeatable fluid measurement without a steep learning curve. Whether you are managing diesel exhaust fluid (DEF) transfers, chemical blending, agricultural inputs, or industrial fluid batching, the ZFM-V delivers +-0.5% accuracy across a 2 to 30 GPM flow range with a display that is actually readable in the field.
What sets the ZFM-V apart from comparable meters is the 3.5-inch full-color backlit LCD -- the largest display available in this product class. Paired with a face-mounted button layout that maps directly to on-screen menu options, this meter can be operated confidently by a first-time user without consulting a manual. The all-in-one calibration procedure eliminates the multiple calibration modes found on competing units, reducing setup time and the chance of calibration errors.
Largest display in class. Full-color backlit screen remains readable in direct sunlight, low light, and dusty field conditions.
Professional-grade precision over a 2-30 GPM range. Suitable for custody transfer, batching, and regulatory compliance applications.
Viton elastomers resist DEF, biodiesel, ethanol blends, and a wide range of agricultural and industrial chemicals.
No external wiring or power source required. Operates on standard AA batteries, making it portable and installation-free.
The ZFM-V tracks two independent totals simultaneously: a resettable batch counter for individual transfer jobs and a cumulative non-resettable totalizer for lifetime volume tracking. Both are displayed on the color LCD at the same time, eliminating the need to switch screens mid-transfer. This is especially useful in fleet fueling, chemical mixing, and agricultural applications where accurate per-job records matter.
Unlike meters that require separate calibration routines for different fluids or flow rates, the ZFM-V uses a single unified calibration procedure. Enter your calibration factor through the face-mounted buttons and on-screen menu -- no tools, no jumpers, no separate calibration mode. Factory default calibration is set for water; adjust as needed for your specific fluid density.
Each physical button on the meter face corresponds directly to a labeled option on the color LCD. Switching units, resetting the batch counter, adjusting calibration, and reviewing totals are all accessible from the home screen in two button presses or fewer. This design eliminates mode-switch confusion common on single-button or two-button meters.
The ZFM-V runs entirely on battery power -- no external 12V connection, no wiring harness, and no need to mount near a power source. This makes it equally at home as a permanent inline meter on a transfer skid or as a portable unit carried between multiple fill points. Battery life is rated for extended use under normal operating conditions; the backlit LCD activates on demand to conserve power.
Pair the ZFM-V with a 12V or 120V transfer pump for a complete metered dispensing setup. For DEF applications, combine with DEF-rated hose, a dry-break nozzle, and a grounded DEF container to prevent contamination. For agricultural chemical transfer, combine with a chemical-resistant pump and appropriate PPE.
