Small, medium and large capacity flow meters

OM Series Small Capacity
OM Series Medium Capacity
OM Series Large Capacity
OM025A001-211 Oval gear meter

OM Series Features:

  • IECEx/ATEX models available, making the product safe to use in flammable liquid applications
  • High accuracy and repeatability, measures every drop and saves waste in your process
  • No requirement for flow conditioning (straight pipe runs) gives a simple and inexpensive installation
  • Extremely versatile design accurately measures high and low viscosity fluids making them perfect for measuring the transfer of thick or non-conductive liquids.

The OM Series Oval Gear flow meter provides exceptional accuracy and repeatability in a wide range of applications measuring clean liquids. With a simple and reliable design concept using only two moving parts, they provide long service life and minimised maintenance costs.

INTRODUCTION

The Oval gear meter is a precise positive displacement flowmeter incorporating a pair of oval geared rotors. These meters are capable of measuring the flow of a broad range of clean liquids.

Stainless Steel flowmeters are suited to most liquid products and chemicals; including many water based liquids, acids, bases and salt solutions, and Aluminium meters are suitable for fuels, oils & most non-aggressive lubricating liquids.

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 totalisers, rate totalisers or batch controllers. These instruments also have monitoring and control output options including 4-20mA, scaled pulse, flow-rate

SIZES & FLOWRATES

OM Series Pulse – Suits 1/8” – 3/8” (4mm-10mm) Pipe Sizes | Flows from 0.5L/hr – 550L/hr with Pulse-Out or LCD Display

The FLOMEC® Small Capacity OM Series Oval Gear meters are well suited to measurement of very low flow rates of various additives, chemicals, fuels, lubricants, and purified waters. Exceptional accuracy and reliability can be obtained on clean liquids of almost any viscosity.
Particularly when flow rates are very low and the viscosity is high, small capacity OM-Series meters provide exceptional performance, while other technologies can provide disappointing results.

OM Series Pulse – Suits 1/2” – 2” (15mm-50mm) Pipe Sizes | Flow rates from 1L/min – 450L/min with Pulse-Out or LCD display

The FLOMEC® Medium Capacity OM-Series Oval Gear meters are well suited to precise measurement of fuels, oils, solvents, alcohols, mildly aggressive chemicals, and various other clean industrial liquids. Flow rates from 1L/min to 450L/min, combined with low pressure drop, weights and measures (A/NZ only) and various hazardous area certifications make the medium capacity OM-Series meters well suited to almost any liquid transfer or dispensing application whether pumped or gravity-fed.

OM Series Pulse – Suits 3” – 4” (75mm-100mm) Pipe Sizes | Flows from 35L/min – 2500L/min with Pulse-Out or LCD display

The FLOMEC® Large Capacity OM-Series Oval Gear meters are well suited to precise measurement of fuels, oils, solvents, alcohols, mildly aggressive chemicals, and various other clean industrial liquids. Flow rates from 35L/min to 2500L/min, combined with low pressure drop, weights and measures (A/NZ only) and various hazardous area certifications make the large capacity OM-Series meters well suited to almost any liquid transfer or application whether pumped or gravity-fed.

OM Series Pulse – Suits 1” (25mm) Pipe Size for Chemical Applications | Flows from 10L/min – 150L/min with Pulse-Out or LCD Display

The FLOMEC® OM025 PPS (Ryton) Oval Gear meters are an exceptionally cost-effective alternative to a stainless-steel meter when chemical resistance is critical, but pressures and temperatures are low.
With internal components constructed entirely from PPS (Ryton) and Alumina ceramic the OM025P Chemical Meter is well suited to precise measurement of non-potable water, fertilizers, herbicides, diesel exhaust fluid, and a wide range aggressive, or corrosive chemicals where standard engineering metals are not suitable.

OM Series Oval Gear Chemical flow meters are an economical solution for measuring an aggressive or corrosive liquid.
** Please confirm chemical compatibility before purchase **

OM Series Mechanical -Suits 1/2” – 4” (15mm-100mm) Pipe Sizes | Flows from 1L/min – 2500L/min with Mechanical Display

The FLOMEC® OM-Series Oval Gear meters with mechanical display are well suited to precise measurement of fuels, oils, and various other clean industrial liquids. This range of meters provides many of the advantages of the electronic version of the OM-Series meters with a rugged mechanical display that provides trouble-free installation and usage in remote areas or areas with no power.
