New Liquid Vortex Flow Sensor Features High Accuracy and Low
Cost
Hudson, MA-Clark Solutions announces the availability of a new
family of liquid vortex flow sensors. DN Series Vortex Flow Sensors
are designed specifically for equipment manufacturers as an excellent choice for
system flow monitoring and control. Combining both high accuracy
and low cost, DN Series Flow Sensors are accurate to 1% fs of
measured value and are available for less than $100 in
quantity.
Suitable for water & water glycol based heat
exchange systems (with the usual additives) and other fluids,
current DN Series models are suitable for flow ranges from 0.9 to
150 liters per minute (0.24 to 39.6 GPM).
DN Series Liquid Vortex Flow Sensors operate on the principle of
Karman's vortex trail. Named after Theodore von
Karman's mathematical description of the phenomenon,
vortex-shedding flow meters present the flow in a pipe with an
obstruction/bluff in the flow meter body. As velocity increases,
alternating vortices are formed on each side of the bluff body and
travel downstream. DN series flow sensors utilize piezoelectric
sensors embedded in an ETFE vane located downstream of the bluff to
detect the generated vortices. The frequency
measured represents the flow velocity. The result is a temperature
insensitive measurement of flow with minimal pressure loss. A flow
factor is provided to convert frequency to volume flow rate for
each model size. Versions with a 1000 Ohm RTD temperature sensor
built-in to the bluff are available, providing direct temperature
measurement in the medium.
