The Trimec Flow Products MP series has long been established as a simple but reliable metering principle providing high levels of accuracy & repeatability for a wide range of liquids from extremely viscous lubricants, chemicals & food bases to non conductive solvents & fuels.

MP Series Quick Guide

What is it?

The Multipulse range of positive displacement flowmeters offer a high level of accuracy and repeatability. These precision flowmeters are used for flow rate measurement in flow monitoring and control applications and for totalising in dispensing and batching. Multipulse flowmeters are suitable for use with a wide range of clean liquids including viscous lubricants, chemicals, food bases and non-conductive low viscosity solvents either pumped or gravity fed.

What is it best used for?

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.

Meter Selection

Meters are selected based on flow range, pressure, temperature, material compatibility and functionality.
Aluminium Multipulse meters are ideal for petroleum products including oils and grease, fuels and fuel oils.
Stainless steel meters are suited for chemicals, water based products and the food, cosmetic and pharmaceutical industries.
PVDF (SAP) meters (20mm size only) ideally suited for special applications associated with corrosive fluid such as sodium hypochlorite, acids, photographic solutions or any chemical
compatible with PVDF.
Multipulse meters are available as blind meters with pulse output or with integral or remote totalisers, flow rate displays or preset batch controllers.
Pulse meter outputs can be interfaced to most electronic displays or instrumentation.

Principles 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.

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.

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.
