The Brodie 9400 Oval gear flowmeter is available for line sizes from 0.5” to 3”, with with flow ranges extending from 5 to 25 L/min up to 100 to 1500L/min.
The three piece body design allows for simple inspection and servicing, without affecting the counter drive: the unit is particularly suitable for high viscosity oils, and in its standard form provides an accuracy of +/- 0.25% for viscosities above 5 cP.
A powerful magnetic coupling drives the output shaft, which is linked to a mechanical totaliser register. A unit suitable for food use is also available.

The BiRotor meter is a positive displacement volume flowmeter, which uses two finely balanced contra-rotating rotors driven by the liquid flow, sweeping a defined volume of fluid with each rotation. The Automatic Pressure Lubricated (APL) version is designed to measure low lubricity fluids such as propane, butane, or natural gasoline, or where abrasive particles are entrained in the flow as occurs with crude oil.A sealed lubricating system isolates all bearings and gears from the process stream and provides long service life.

The mechanical output meter shaft allows mounting of electro-mechanical accessories for control, batching, totalising and printing.

The BiRotor meter is a positive displacement volume flowmeter, which uses two finely balanced contra-rotating rotors driven by the liquid flow, sweeping a defined volume of fluid with each rotation. BiRotor meters are used in the most demanding applications in the petroleum industry, where ruggedness, accuracy and long life are important.

Mechanical meters use a gear train, located outside the measuring unit chamber, to totalise the liquid throughput on a mechanical or electronic totaliser. The meters cover size ranges from 1.5” to 16” lines.

Long life is assured because the meter does not contain any oscillating, reciprocating or sliding parts or cranks to wear or disturb the balance.

The BiRotor Plus is a volumetric flow measuring device that produces high resolution signals directly proportional to the rate of liquid flow through the meter. These signals are amplified and shaped by an internal preamplifier mounted directly on the meter. The meter can accommodate up to two signals that can be transmitted to accessories such as totalizing counters, digital readout devices, or control equipment for interpreting data. The meter is unique in that it does not use any sliding vanes or reciprocating parts, nor are there any shock loads on the mechanism during operation resulting from the shifting of off-balance masses. measure liquid flow through the meter. 1.2 Meter Model Number The model number, serial number, flow range, and operating pressure appear on the nameplate attached to the meter body.

The Flowmate Micro Oval is a high accuracy positive displacement flowmeter designed to measure low flowrates of liquids. Suitable for use in Hazardous areas (via suitable barrier). The well known oval gear principle and the application of new material technology are combined in this low cost but high precision device. Typical applications include adding colours/dyes/essences to processes, anti-foam additive to reactors and pilot plant flow totalisation.

Trimec's Multipulse PD flowmeters utilize the widely accepted oscillating piston design principle with the performance enhanced by the use of modern engineering materials to provide a cost effective and reliable solution for a wide range of industrial flow measurement applications.

Principle Of Operation

The valves are pilot operated and operate on a balanced piston principle, spring biased to a closed position. Pressure differential overcomes the force of the spring, causing the main valve to open and establish flow. The pilot varies the pressure on the spring side of the piston for position.

Design Features:

• Modular construction - All internal parts including seat ring can be removed with the cylinder assembly without disturbing line connections.

• No diaphragms or stuffing boxes

• 45° body design assures high capacity

• Positive shut-off

• Uniform speed of response

• Linear control characteristics

• Inherently checks reverse flow
