Key Features & Capabilities
The FM-120 is engineered for reliability, ease of use, and precision measurement in demanding fuel transfer environments.

The FM-120 4 Digital Fuel Oil Flow Meter is a high-accuracy, 4-digit mechanical display meter designed for diesel, kerosene, and gasoline measurement. Featuring a 1" NPT inlet and outlet, this meter covers a flow range of 20–120 L/Min with a meter accuracy of ±1%. Its robust aluminum housing and precision internal gear mechanism make it ideal for industrial fuel dispensing, fleet refueling, and agricultural fuel monitoring.
The mechanical 4-digit counter displays cumulative flow volume in Liters or Gallons and can be manually reset to zero for batch measurement. The non-resettable accumulation register ensures a permanent record of total throughput.
Applications:
Diesel fuel dispensing and monitoring
Kerosene and gasoline flow measurement
Agricultural and fleet fuel management
Industrial transfer and batch metering
