macnaught flow measurement

The M & MH range from Macnaught are positive
displacement oval gear flowmeters that are designed to
cover a broad range of industrial fluid measurement
applications. With versions covering high temperature,
high pressure, as well as hazardous locations, there is a
Macnaught Industrial flowmeter to fit virtually any
industrial liquid measurement requirement.

Macnaught Industrial Flowmeters are constructed utilizing a robust

stainless steel body suitable for use in the harshest environments.
Our bearing-less PTFE/PPS rotors provide exceptionally low
pressure drop and can even be used in gravity fed applications.

This unique rotor design ensures minimal wear resulting in many
years of reliable service. This approach has proven over time to

rovide consistently accurate flow measurement that is not

p
affected by variations in temperature, viscosity, or pressure.

Another benefit of our unique rotor design is simplicity of repair.
With only 2 moving parts, our meters are simple to repair, require

inimal repair parts stock, and can even be repaired inline, resulting

m
in less downtime.

Oval gear flowmeters are ideally suited to applications requiring

ccurate dispense quantities. Measurement of very low flow

a
rates, pulsating flow, small batch sizes, viscous products, and
non-conductive liquids are all ideal uses for oval gear meters.
Because these meters don't require flow conditioning, no straight
piping runs are required, so they can be used in installations where

space is limited without effecting performance.

With 12 mechanical and digital display options to choose from,
Macnaught flowmeters are the perfect choice to suit virtually any
application requirement.

Meter Selection

Step 1 Verify Fluid Compatibility & Application Conditions

Determine if your fluid is compatible with the wetted parts of the

eter. All wetted parts are made from: 316SS, FEP, and PPS. Also

m
determine if the Pressure and Temperature are within the stated limits.

Tips: If the temperature is between 80-120C, use high
temperature SS rotors (step 4).We also offer high pressure models
if the operating pressure is beyond the limits of our standard
Industrial meters.

Step 2 Choose the model based on your flow rate (

Tips: If possible, choose a meter model where your expected flow

ates fall between 20-80% of the maximum flow range for

r
optimum performance. If you are measuring a high viscosity fluid
(over 1000cp), the maximum flow range will be lower. You should
consult the factory if you are unsure which model you need.

see Flow Range Chart)

Step 3 Choose your connection thread type

Tips: We also offer flange adaptor kits for all of our meters from

M025 and larger (see step 6). We offer ANSI 150, DIN PN16, and
JIS flange adaptors. Our adaptors can be fitted to any of our
meters regardless of the threaded connection type. Flange
adaptors are ordered separately in step 6. Please note that if you
order a mechanical meter and want NPT threads with display in
Litres, a type "3" connection should be specified. Also note that
the F050 and larger meters do not include threaded connections.
The adaptors must be ordered separately.

Step 4 Choose Rotor Type

Tips: Choose high viscosity rotors if the fluid is above 1000cp. If

the fluid is between 100 and 1000cp and the flow rate is over
50% of the maximum rated flow of the meter, high viscosity rotors
can be used if lower pressure drop is required.Choose High
Temperature SS rotors if the process temperature will be between
80-120C.

Step 5 Choose Mechanical Display or Pulse Output options

Tips: Choose a pulse output if you want to use a digital display.

The Digital displays are listed in the next step and can either be
mounted on the meter or remotely.Our standard pulse output
comes with both hall effect sensor and reed switch outputs. If
you are installing the meter in a hazardous environment, you can
choose option "2" which will give you 2 reed switches, which
classifies the electrical output of the meter as a "simple device".

Step 6 Choose Accessories (

Tips: All of our digital displays can be mounted either locally on

the meter itself, remotely on a wall, on a panel, or nearby on the
piping. Just choose the functions you need and the housing type
you require. If you are looking for flanged end connections, you
can also order the appropriate flange type here. Our strainers all
come with the appropriate mesh size for the meter that they fit,
so the connection size is the only choice you need to make.
