Meriam Orifice Plates &
Accutubes
Meriams Accutube Flow
Sensors are lab-tested and
field-proven flow elements
perfect for gas, liquid or
steam service. With
thousands in use
worldwide, the Accutube
continues to be the right
choice when ease of
installation, cost
effective operation and
highly accurate
performance is required.
The Accutube averaging
Pitot tube is a head type
device, which generates a
differential pressure
signal similar to the
orifice, venturi, flow
nozzle, and other head
producing primary
elements. It can be used
for flow measurement only
or with static pressure
and temperature
transmitters as the
primary measurement source
for a flow control loop.
It has been proven that
the Accutubes flow
measurement accuracy is
better than that of the
orifice. The Accutube also
generates considerable
cost savings with its
simple installation and
wear-free,
energy-efficient design,
providing a
viable alternative to
traditional flow
measurement devices.
