High Pressure Small OM Series 1 1

Small Capacity High Pressure Oval Gear Meters

The Small High Pressure Oval Gear Meters from FLOMEC is part of the OM-series, and offer the ability to handle a wide range of fluid viscosities because of the increased flow range. This high pressure version provide volumetric measurement of low flow, clean liquids up to 400 bar.

More advantages:

  • Direct volumetric reading, which gives high accuracy and repeatability
  • Measures liquids both of high and low viscosity
  • No requirements for flow conditioning
  • Optional Exd I/IIB approval (ATEX, IECEx)
  • High pressure rated up to 400 bar (5580 psi)

High accuracy and repeatability

The Oval gear meter is a precise positive displacement flowmeter incorporating a pair of
oval geared rotors. The meter is, therefore, independent of viscosity and density, which means that the same high accuracy is obtained regardless of changes in the physical parameters.

The high accuracy is also achieved because of the direct volumetric reading, which also gives a high degree of repeatability. 

Monitoring for precision

Oval Gear flowmeters are available as blind meters with a pulse signal output capable of
interfacing to most monitoring and control instrumentation.
Or the meter can be fitted with instruments such as totalizers, rate totalizers or batch controllers.

These instruments also have monitoring and control output options including 4-20mA, scaled pulse, flow-rate
alarms and batch control logic (preset metering).

High Pressure Small OM Serie

Typical Applications

These flowmeters are capable of measuring the flow of a broad range of liquids, and suitable for applications including:

  • Metering lubricants
  • Chemicals
  • Grease
  • Additives
  • High viscosity fluids

Usage in the maritime industry

Flomec OM-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 OM-series flowmeter provide you with an accurate and reliable measurement of its fuel consumption.

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.
