MX Flow Meter Series’s versatility and durability in all environments
Macnaught have been adding to their versatile
MX series offering more options for hazardous environments as well as safe
environments.
The Australian-owned designer and manufacturer of flow meters
and fluid transfer instruments were first established in 1948, meaning over 70
years of flow experience. With their oval gear technology and revolutionary
modular design, Macnaught’s MX Intrinsically Safe Industrial Meters are offering
their clients their most advanced positive displacement oval gear flow meters. The
MX Ex are ATEX approved, rated Ex ia IIC (Class 1 Zone 0), approved CSA and FM
and manufactured from robust stainless steel (316). This allows oval gear
technology to be used in applications requiring precise flow measurement in
hazardous areas.
Oval gear flow meters measure the volumetric flow rate of
a moving fluid, the two rotating oval gears divide the material into fixed, metered
volumes. They have been widely recognised as one of the most versatile,
accurate flow measurement solutions that are not affected by variations in
temperature, viscosity, or pressure. Maintenance on these meters are minimal
too because the moving parts inside the meter body are limited to the pair of robust oval
gear rotors.
The MX
Ex flow meters are ideal for the precise transfer or dispensing of thin or viscous
fluids, corrosive chemicals and non-conductive liquids in environments where
there is the potential of exposure to flammable gases, or vapours. This
operating principle means that the meters do not require flow conditioning or
straight pipe runs and can be used in installations where space is limited
without a detrimental effect on performance. The MX-Series meters can also be
easily and efficiently dismantled, serviced and reassembled whilst still in the
line, and without the need for any special tools or training.
The MX Ex series are available in ¼” (8mm) up to 2”
(50mm), with flow ranges from 0.13 GPH to 132 GPM and an accuracy of ±0.5%. They
are equipped with Macnaught’s versatile M-Lock mounting system,
allowing the pulsers and displays to be installed and exchanged in less than 15
seconds. Therefore, these oval
gear flow meter displays can be replaced without having to disassemble the
meter or remove it from service. A quarter turn is all that would be required
to change pulse modules or replace with an LCD Screen.
Macnaught offer two models
of pulser approved for use in hazardous areas, the first is the MXD-BS; an
intrinsically safe (Ex ia) NPN open collector, ATEX, IECEx, CSA and FM approved
with an IP67 rated housing for use with temperatures up to 85˚C. The second
pulser is the MXD-CS; a flame-proof (Ex d) NPN open collector, also ATEX,
IECEx, CSA and FM approved with an IP67 rated housing for use with temperatures
up to 85˚C.
Each meter is individually tested and calibrated
before dispatch as well as being able to gain access to a full range of spare
parts that are readily available. Finally, all
MX-Series meters are backed with a 2 year factory warranty.
Bell Flow Systems Ltd, a leading supplier of flow
measurement solutions and a UK distributor for Macnaught are pleased to offer
