Open Channel Flowmeter UVH-2000

for Sewage, Wastewater or Industrial Effluent
Accurate and Stable flow measurements for Open Channel with Ultrasonic Pulse Doppler technology

UVH-2000 is flowmeter constituted with velocity meter and level gauge to measure flows of sewage, wastewater, industrial effluent and other effluents contain fine particles, sludge or fine bubbles through pipes or open channels with free water surface. UVH-2000 velocity meter employs the Pulse Doppler method that provides flow velocities of multi points on ultrasonic beam, and ultrasonic level gauge that measures water level without contact. UVH-2000 is suitable for applications such as in maintenance or flow management of industrial effluents, public utilities, sewage plants or sewerage systems.
Typical applications
UVH-2000 measures velocity of flow which contain fine particles or slurries such as sewage and wastewater.
Features
• Accurate and stable measurements are realized with Ultrasonic Pulse Doppler technology.
• Two measurements - water velocity and water level - are used to calculate flow rate, therefore UVH-2000 can be measured flows subject to backwater due to obstacle in a stream, reverse-flows, or etc.
• Obstacle installed in the stream is very small so there is no head loss or buildup of sediment.
• Flow measurement is possible over the full range from zero to full water levels.
• Transducers are installed in flow channel easily and can be accomplished without modifying existing channel.
• Whenever flow velocity distribution is not developed enough due to short, straight channel lengths, etc, stable measurement can be obtained, because multi points and multi paths (up to 4 paths) measurement are possible.
• Water level is measured by ultrasonic level gauge without contact (Radar level gauge is available as optional).
Pulse Doppler Flow Velocity Measurement
• Only one transducer is needed for one path measurement as transmitter and receiver.
• Flow velocity is calculated based on the Doppler Shift resulting as ultrasonic waves are reflected
from moving particles or bubbles in water.
• Pulse Doppler method enables measurements of flow velocity at multi positions on an ultrasonic
beam.
• Multi point and multi path measurements enable stable measurement even if flow is not
developed enough.
