The oval gear mechanism measures the volume of compatible liquids as they pass through the meter. Its mechanical display provides a direct reading for fuel transfer and oil distribution operations.
The resettable subtotal counter supports individual dispensing tasks, while the non-resettable total counter records cumulative volume for ongoing use.
The aluminum body helps keep the meter compact and lightweight for integration into compatible liquid transfer equipment.
The meter can be configured for litre or gallon display upon request. Its design supports horizontal or vertical installation to suit different equipment layouts.
It is designed to measure the volume of compatible liquids during transfer or dispensing. Typical applications include diesel transfer, petroleum distribution, and industrial oil measurement.
The listed flow range is 5–80 L/min, with an accuracy of ±0.5%. These specifications should be considered alongside the liquid properties and operating conditions.
The supplied product information states that this meter is not suitable for water. Use it only with liquids compatible with the meter’s materials and measuring mechanism.
The 4-digit subtotal counter can be manually reset for a new dispensing operation. The 8-digit total counter records cumulative volume and cannot be reset to zero.
Confirm the required flow range, liquid compatibility, 1-inch connection thread, display unit, and installation orientation. Buyers should also confirm whether the connection needs BSP or NPT threads, as these are different standards.
Do not use this meter for water. The supplied product information recommends installing a suitable filter before the meter to help prevent foreign particles from obstructing the measuring mechanism. Follow the applicable operating and calibration instructions for installation and accuracy adjustment.

1.There is no calibration function on old oval gear volume flow meter.so we add correction function on this new meter.it’s very convenient to operate.
2.The Liquid part and the measurement part uses magnetic transmission.which will never leak.
3.The gear design is based on different working conditions.there are PPS.aluminum alloy.and stainless steel matericals.

1.If the real volume is 99 and flow meter show 100.you only let adjusted bolts out.
2.If the real volume is 100 and flow meter show 99.you only let adjusted bolts in.
OGM25-0.5 aluminum oval gear meter has the ability to handle a wide range of fluid viscosities with exceptional levels of repeatability and durability ,applying in the petroleum,chemical,food industry etc,and it has big advantages as follows:
1.Low pressure drop.
2.Compact sixe,easy maintenance.
3.Easy to read and operate mechanical dispaly.
4.Horizontally and vertically flexibility of installation options .
5.5-digital sub-total.with floating point from 0.01 to 99999.99,7-digital non-resettable totalizer.
6.3.6v lithium battery power,durable service.
