Flow 5
The Flow 5 open channel flowmeter provides comprehensive flow
monitoring with data logging and control functions for a complete range of
flumes, weirs and channels. Flow calculations to the British Standard
BS3680 are available within the software together with calculations for a
wide variety of other primary elements. For applications where there is no
primary element, the optional 4-20mA input can be used to connect a
Doppler Velocity Sensor (available from Pulsar) to enable the calculation of
Flow Q = Velocity x area, for a wide range of channel shapes. Also,
available within the unit is a customised 32-point calibration routine which
also permits the flow measurement of non - standard flumes and weirs.
The Flow 5 can measure from 0.0 m to 15 m from the transducer to the
surface being monitored, dependent on the transducer used. The Flow 5 can
show details of
level , space , distance , head or flow on the display along
with a totaliser if desired.
The five user-definable relays with individual setpoints can be programmed
to activate devices such as pumps, samplers, remote totalisers or other
control equipment. The 4-20 mA output is fully programmable to provide
an output relative to
level , space, distance, head or flow .
