Product Advantages

Compact Mechanical Design

The FM150-0.5 combines an oval gear measuring mechanism and mechanical counter in a compact housing, making it practical for fuel transfer and oil distribution equipment.

Clear Measurement Display

The mechanical display provides visible flow readings without relying on a digital screen. The resettable subtotal counter supports individual dispensing operations, while the total counter records cumulative volume.

Magnetic Transmission

Magnetic transmission transfers movement from the measuring mechanism to the counter without a direct mechanical connection, supporting reliable operation.

Flexible Installation and Unit Selection

The meter supports horizontal or vertical installation. Litre or gallon display options can be requested to suit different market preferences.

FAQ

1. What liquids can the FM150-0.5 Oval Gear Flow Meter measure?

The FM150-0.5 is intended for diesel, compatible petroleum products, and other liquids suitable for its materials and measuring mechanism. It is not recommended for water according to the supplied product information.

2. What is the difference between the subtotal counter and the total counter?

The 4-digit subtotal counter can be reset manually for an individual transfer or dispensing operation. The 8-digit total counter records cumulative measured volume and cannot be reset to zero.

3. Can the FM150-0.5 display gallons instead of litres?

Yes. The measurement unit can be changed from litres to gallons upon request. Confirm the required unit when ordering.

4. Can the FM150-0.5 be installed horizontally or vertically?

The product information indicates that the meter supports horizontal and vertical installation. The piping arrangement should allow the liquid to flow through the meter in the intended direction.

5. What should buyers consider when selecting an oval gear flow meter?

Check the required flow range, liquid compatibility, connection thread, display unit, and installation arrangement. For this model, the listed flow range is 5–80 L/min and the connection is BSP / NPT 1″. Confirm the required thread standard before ordering.

Important Usage Information

Do not use this meter for water. The supplied product information also recommends installing a suitable filter upstream to help prevent foreign particles from obstructing the measuring mechanism. Follow the product’s operating and calibration instructions when adjusting measurement accuracy.
