Measures Velocity + Level to Monitor Flow with Multiple Ultrasonic Sensors
Monitor flow through large open channels, partially full sewer pipes and surcharged pipes without a flume or weir. Designed for municipal stormwater, stream flow, irrigation water, raw sewage, sluiceways, water intake channels, cooling water discharges and industrial effluent.
The AVMS 5.1 uses three submerged ultrasonic sensors to continuously measure both Velocity and Level in the channel. It is recommended for large channels or applications where velocity will vary across the width of the channel.
The sensors resist fouling, corrosion and abrasion. The flowmeter can be configured with three standard submerged velocity-level sensors, or with three submerged velocity plus a separate non-contacting ultrasonic level sensor.
How it Works
The AVMS 5.1 Area-Velocity Flow Meter measures level and average velocity from multiple sensors to calculate flow in open channels or pipes. The system includes the AVMS 5.1 flowmeter with interconnect cable to a multi-sensor enclosure plus three submerged ultrasonic sensors.
The ultrasonic velocity sensors mount in the channel in positions where they will be submerged. Stainless steel mounting brackets are included. The sensors are completely sealed with no orifices or ports. Level is measured by connecting the built-in level sensor from any one of the three velocity sensors, or with an optional non-contacting ultrasonic level sensor.
Channels of any shape can be monitored. Forward and reverse flow can be measured and totalized. View flow rate and total flow on the large backlit LCD display and connect to external devices with three 4-20mA outputs and two control relays. The AVMS 5.1 measures flow velocity from 0.1 to 20 ft/sec (0.03 to 6.2 m/sec) and reverse flow up to 5 ft/sec (1.5 m/sec).

Measure open channel flow without a flume or weir.
An Area-Velocity Flow Meter continuously measures both Level and Velocity to calculate flow volume in an open channel or pipe.
The ultrasonic sensor is installed at the bottom of a pipe or channel. To measure water level the sensor transmits ultrasonic pulses that travel through the water and reflect off the liquid surface. The instrument precisely measures the time it takes for echoes to return to the sensor. Based on the speed of sound in water, the level is measured with accuracy of ±0.25%.
Flow velocity is measured with an ultrasonic Doppler signal continuously injected into the water. This high frequency sound (640 KHz) is reflected back to the sensor from particles or bubbles suspended in the liquid. If the fluid is in motion, the echoes return at an altered frequency proportionate to flow velocity. With this technique the instrument measures flow velocity with accuracy of ±2%.
Greyline Area-Velocity Flow Meters work in partially full and surcharged pipes, rectangular, trapezoid and egg-shaped channels.
Optional - Separate Level and Velocity Sensors
A separate down-looking ultrasonic sensor can be used for highly aerated or turbulent flow applications. It measures level by transmitting ultrasonic pulses through the air to the liquid surface with accuracy of ±0.25%. Along with the level sensor, a submerged Doppler velocity sensor is used to measure the water velocity.
