High-Precision 4-Digit Mechanical Flow Meter for Non-Commercial Fuel Measurement

Reliable 4-Digit Mechanical Flow Meters for Accurate Fuel Dispensing

Mechanical flow meters, recognized globally as “rotary fuel meters” (USA), “mechanical flow gauges” (UK), “机械流量计” (China), “มิเตอร์การไหลเชิงกล” (Thailand), “meter aliran mekanik” (Indonesia), and “ម៉ាស៊ីនវាស់ចរន្តយន្តកាស” (Cambodia), are trusted tools for precise liquid measurement in non-commercial applications. These meters are widely used for fuel dispensing, industrial liquid transfer, and mobile operations where electricity is not available.

The FM-120L series stands out with its unique 4-digit resettable subtotal counter, allowing operators to track individual dispensing batches with precision, while the 8-digit total counter records cumulative usage permanently. This feature makes it easy to monitor and manage fuel flow, ensuring accurate measurement for each transaction or operation.

Built from durable plastic and aluminum, the FM-120L offers ±1% accuracy and a flow range of 20–120 L/min. Its 1″ nutating disk system provides consistent, reliable readings, and the mechanical readout with rotating wheels ensures that measurements can be read clearly at a glance without electricity. A pipeline strainer is recommended to prevent debris from affecting accuracy.

Designed for ease of installation and on-site calibration, the FM-120L is lightweight, robust, and highly dependable. It is perfect for non-commercial settings such as small fuel stations, farms, workshops, or remote fueling sites. Operators worldwide rely on its simplicity and precision to manage fuel and other low-viscosity liquids safely and efficiently.

By integrating the FM-120L 4-digit mechanical flow meter, users gain batch-level control, accurate fuel tracking, and reduced operational errors. Lightweight yet sturdy, and with an easy-to-read mechanical display, it is an ideal solution for precise non-commercial liquid management across diverse environments.
