How Doppler Flowmeters Work
| Doppler ultrasonic
flowmeters operate on the Doppler shift principal
, whereby the transmitted frequency is altered linearly
by being reflected from particles and bubbles in the
fluid. The net result is a frequency shift between
transmitter and receiver frequencies that can be directly
related to the flow velocity. If the pipe internal
diameter is known, the volumetric flow rate can be
calculated. Doppler meters require a minimum amount
of solid particles or air in the line to achieve measurements.

Measure flow from outside a pipe. The
EESIFLO 3000 is ideal for "difficult liquids"
that would damage regular flow meters - wastewater, slurries,
sludge, chemicals, viscous liquids and abrasives. There
is no obstruction to flow and no pressure drop. The standard,
strap-on ultrasonic sensor fits any pipe 1 inch and above
Use the isolated 4-20mA to transmit flow to remote displays,
recorders or controllers. The 3 programmable relay can
be used for flow control, pump protection or flow proportionate
pulse. Display and totalize flow in your choice of engineering
units (gallons, liters etc.)
Sensor cable can be extended by the user using standard
signal cables since a pre-amplifier is supplied as standard
no loss of signal. |
