Established in 2011 and based in Melbourne, Australia is an ISO9001:2008 certified company that manufactures a range of multi-pulse rotary piston flow meters and supplies a full range of positive displacement flowmeters throughout the world.

Trimec Flow Products markets the Dimak range of oval gear flow meters and a proprietary range of positive displacement rotary piston, insertion and impeller flow meters, ancillary flow hardware and dedicated electronic flow instrumentation from Trimec Industries.

The meters measure the flow of clean liquids and are produced in a wide variety of materials and configurations to suit most markets including the water, food, chemical, cosmetic, ink, pharmaceutical, paint, petroleum and additive industries.

PRINCIPLE OF OPERATION

Liquid enters into a precision machined chamber which contains an oscillating piston. The position of the piston divides the chamber into compartments containing an exact volume. The liquid pressure causes the piston to oscillate and rotate its centre hub. The movements of the hub are sensed through the meter wall by a series of magnets. Each revolution of the piston hub is equivalent to a fixed volume of liquid, which is indicated as flow by an indicator or totaliser. Close clearances between the piston and the chamber ensure minimum slippage of the liquid for highly accurate and repeatable measurement of each volume cycle.

APPLICATIONS

Applications include alcohols, acetic acid, caustic soda, ethanol, fuels, grease, glucose, ink, insecticides, latex emulsions, liquid sugar, margarine, mayonnaise, molasses, resin, tallow, urethane, water, xylene & liquid yeast.

Features

• Insensitive to mounting orientation.
• Measure low & high viscosity liquids.
• Has only one moving part (oscillating piston).
• Has no stagnate chambers to accumulate contaminants or stale products.
• Certified Exd hazardous area versions in all sizes.
• No need for flow conditioning (straight pipe run etc).
• Limited number of spares parts needed to support the product.
• Extremely compact and comparatively lightweight.

The Dimak Micropulse Oval series PD flowmeters offer a high level of accuracy turndown & repeatability. These precision meters are used for flow rate measurement in flow monitoring & control application and for totalizing in dispensing and batching. Micropulse gear meters are suitable for use with a wide range of clean liquids including viscous lubricants, chemicals, food bases & non-conductive low viscosity solvents either pumped or gravity fed.

The Oval Gear Flow meter uses two fine-toothed meshed gears that are oval in shape and engage each other in a precision machined body. This fluid is transferred sequentially from the inlet to the outlet and one ore two pulses are transmitted for each revolution of the gear. Embedded within the gear, a pair of chemically resistant magnets provide the external signals. Detection of the rotation uses either a reed switch or a Hall effect sensor on the outside of the fluid housing. A choice of materials allows the meters to be used in a variety of corrosive applications.

The equipment is suitable for use in hazardous areas, and the basic meter is classed as simple apparatus, enabling use in monitoring flows of low viscosity hydrocarbons, fuels and solvents.

FEATURES

• High accuracy repeatability.
• Measure low high viscosity liquids.

The basic construction of turbine flow meters includes a bladed turbine rotor which is axially suspended in the pipe.  As the fluid flows through the pipe, it causes the rotor to spin on its axis at a speed which is proportional to the velocity of the fluid.  The passage of each rotor is sensed by the turbine meter using gears, photoelectric cell or magnetic pickup installed on the outside of the flow tube or the meter body, adjacent to the perimeter of the rotor.

TM Turbopulse mini & the larger TP Turbopulse turbine series measure flows of low viscosity liquids from 3 to 7,000,000 litres/hr in a range of sizes from 1/4″ to 24″ (6mm~610mm).

The TM mini series have a tangential rotor with integral flow conditioning ports whilst the TP series have an axial rotor and flow guides, the TP series needs to be installed in straight sections of pipe either horizontal or vertical so that the flow is conditioned. The TP series have Exd & Intrinsically Safe (I.S.) approvals. Meters are available in Flanged or Threaded versions.

Both meter series are robust, compact & take little space in the piping system. Applications include fuels, alcohols, solvents, insecticides, milk, chemicals, water & light hydraulic oils.

FEATURES

• High accuracy & repeatability.
• Low cost of ownership, wide flow range.
• Rugged & compact design.
• Certified Exd & I.S. hazardous area versions.

The Trimec Dualpulse insertion paddle wheel flow transducer is a cost effective means of accurately measuring the flow of water, water-like liquids or a wide variety of low viscosity liquids in completely full, large diameter pipes. The sensor is inserted into the process piping via a suitable fitting. Liquid flow through the pipe results in rotation of the affixed paddle wheel. The rotational speed of the paddle is proportional to the flow velocity, and therefore, proportional to the flowrate in the pipe.

The insertion type design provides a measuring technique that is much less expensive than full bore flowmeters, especially in larger pipe sizes. Insertion paddle wheel sensors are a robust measuring technology that boasts exceptional tolerance to dirt and solids.

FEATURES

• All stainless steel construction
• Suits pipes 40~2500mm (1.5~100″)
• Low installed cost
• Simple to install
• Unique head design to extend linear measuring range
• Two independent pulse outputs with high noise immunity (CE compliant)
• High pressure submersible design
• Hot tap option

DP490 & DP525 are cost effective stainless steel flowmeters for measuring the flow of liquids in pipes sizes 1.5″~100″ (40~2500mm).

Insertion flowmeters are installed with the metering head 1/8th into the pipe resulting in very little pressure drop. They do not require external power when used with the Trimec rate totalisers however some options such as high temperature & non-magnetic models require external power.

Applications include HVAC, hot & chilled water, fire systems, water distribution (management & treatment), boiler feed water & hydrant flow testing.
