GE-104D portable doppler flow
velocity meter could measure the liquid velocity in open
channel or river, it could measure the depth of water too.
It could supply Instantaneous flow rate and totalized flow
value, 265M built-in internal memory with 4G SD card, The
GE-104D dopper flow velocity meter could remote measure by
GPRS wireless module(optional accesory)
GE-104D ultrasonic Doppler flow velocity meter is a compact,
easy-to-use system for measuring the velocity and depth of
water in rivers and streams, open drainage channels, and
large non-full pipes. It is suitable for use in a wide range
of water qualities ranging from sewage and wastewater to
clean streams, potable water, and even sea water. The
doppler velocity meter measures forward and reverse flow
conditions and may be programmed to compute flow rate and
total flow in pipes and open channels.
Liquid water velocity is measured by the ultrasonic doppler
principle which relies on suspended particles or small air
bubbles in the water to reflect the ultrasonic detector
signal. The doppler flow velocity meter will not operate in
very clean, degassed water. Water depth is gauged by a
hydrostatic pressure sensor, referenced to atmospheric
pressure through the vented power and signal cable.
