Oval Gear Meter
The Brodie Oval Gear Flowmeters are positive displacement meters designed for use in the Chemical Processing, Industrial, Food and Beverage, and Hydrocarbon processing industries.
Utilizing precision matched oval gears for exact liquid measurement, these high-performance meters are virtually unaffected by changes in viscosity and maintain accuracy even when handling low viscosity products at low flow rates.
The Oval Gear Meter is available in three output configurations:
- Mechanical
- Smart Meter Manager
- Power Pulse

Viscosity changes have little effect on Brodie’s Oval Gear Flowmeter. At full flow, the change in error % is negligible.
Brodie’s Oval Gear meters are supplied in a 3-piece design, which uses both a top and bottom flange in place of the closed-end body configuration found on previous models. This 3-piece design meets or exceeds all of the design and performance specifications of the original oval gear meter while offering several distinct advantages.
Mechanical power transmission for the 9400 Series is established using a proven ‘Type 7’ magnetic coupling, outside of the flow stream, to drive a variety of accessories in a number of applications. Electronic registration for the 9800/9900 Series is provided through the Brodie electronic register. This microprocessor based instrument is used for flowrate indication and totalization. It is capable of transmitting a factored analog current output signal (4-20 mA) used to drive standard process instrumentation.
ADVANCED ELECTRONIC FEATURES
Only available in the 9900 Model, the Smart Meter Manager™ provides an array of useful utilities:
- Automatic temperature compensation
- 4-20 mA (2-wire mass/volume) output with HART® communication
- User configurable and scalable pulse output
- Comprehensive alarms for both process flow and internal diagnostic checks
