High accuracy and repeatability

The EGM-series oval gear meters is a precise positive displacement flowmeters incorporating a pair of
oval geared rotors. The meters are, therefore, independent of viscosity and density, which means that the same high accuracy is obtained regardless of changes in the physical parameters.

Thus, the EGM-Series will generate accurate and reliable measurement of almost all clean liquids.

Additionally, you will get a flowmeter, that gives a high degree of repeatability because of the direct volumetric reading.

Monitoring for precision

The Oval Gear Flowmeters from the EGM-Series offer a pulse signal output capable of interfacing to most monitoring and control systems, such as a PLC or DCS.

Moreover, the “Fuel Consumption” option can tolerate flow pulsations and has an inbuilt temperature sensor to correct for the fuel density changes.

The cable output from the flowmeter can also be wired to instruments such as totalisers, rate totalisers or batch controllers.

Besides, the flowmeters can be acquired with monitoring and control output options including 4-20mA, scaled pulse, flow-rate alarms, and batch control logic (preset metering).

Typical Applications

Aluminum meter with PPS rotors

Oils
Greases
Fuels
Fuel Oils

Aluminum meter with SS rotors and Bronze bearings

Fuels with high Benzene content
Automotive Brake Fluid
Solvents such as Turpentine

Stainless Steel meter

Alcohols
Water-based Liquids
Some Aggressive Liquids
AdBlue (DEF Urea)
Fuel and Oil applications in saline marine environments

Usage in the maritime industry

Flomec EGM-series is especially suitable for flow measurement / dosing of more viscous liquids such as oils, fuels and bunker C Fuel Oil.

Measure your fuel consumption

For an application such as fuel supply to a surplus dosing engine, both flow and return flow must be measured to achieve net consumption.

In addition, the temperature must be measured for volume compensation. For this we also provide temperature sensors and flow computers with standard API / ASTM tables defining the different fuel types.

Setting up a system using the EGM-series flowmeter provide you with an accurate and reliable measurement of its fuel consumption.

Choose the right Flowmeter

The Oval Gear Meters use a measuring principle, where a pair of oval-shaped gears in a measuring chamber rotate by the force of the liquid on these. The liquid flows into a chamber and is sealed off once the chamber is full and produces either an electronic pulse or drives a gear to register the volume as it exits the chamber.

As illustrated in the example on the right, the pulse is generated because the (green) liquid is sealed from both the inlet (red liquid) and exit (blue liquid). This set up would produce four pulses as the meter transmits four identical volumes for every cycle.

This matters because the simplest meters register each time a bucket is filled. Here the total volume would be the sum of the number of buckets filled. In the complex meters the discrete volumes passed each time can be summed together to see the overall volume passing through the meter.

Accessories

When you buy the Oval Gear Meters, they each, by default, contain a traceable calibration certificate and 2 pulse outputs in the form of a Reed contact and Hall effect sensor.

This means, that it can be used to either have dual resolution of the heart rate signal or as a backup.

Additionally, there is a wide selection of different LCD display types associated with this series, so you can get a display of the values for instantaneous flow (eg l / h or m³ / h) and total flow (eg l or m³).

You also have the option to get a traditional mechanical display.

What power supply is required for pulse output models?

The pulse models typically operate on 5–24V DC, depending on the specific configuration.

How is the OM Series installed?

The meter should be installed horizontally or vertically, ensuring proper flow direction, avoiding air bubbles, and allowing for accurate fuel consumption measurement.

Maintenance Tips for Optimal Performance

These meters are designed for long-term reliability with minimal maintenance, but periodic cleaning and inspection of the oval gears and seals can help maintain accuracy.

What should I do if my FLOMEC flow meter is not providing accurate readings?

Check for:

Proper installation (eliminating trapped air and flow pulsations)
Correct calibration for the liquid being measured
Debris or wear affecting the oval gears

Can I recalibrate my FLOMEC OM Series flow meter?

Yes, the meter can be field-calibrated to ensure repeatability and accuracy over time.

Selecting the Right Meter for Your Needs
