3. PRODUCT DESCRIPTION
The IS-6000 Doppler stationary ultrasonic flow meter continuously measures the flow of water and wastewater in pressurized
and partially filled pipes and in open channels with water depths from 1.5…80 in. (0.04…2 m).
As a standard, the flow meter consists of a transmitter and an ultrasonic area velocity sensor for combined velocity and
water level measurement (see Figure 1). Discharge is then calculated by multiplication of the average flow velocity and the
wetted cross-sectional area. The transmitter allows connection of up to 3 ultrasonic area velocity sensors for simultaneous
measurement at up to 3 different measurement spots in one cross-section.
Alternatively, additional external water level sensors (for example, a hydrostatic level sensor or an ultrasonic down-looking level
sensor) can be connected to the system depending on specific site conditions, providing accurate water level measurement in
case of water level fluctuations.
For discharge measurement in pressurized and partially filled pipes, insertion sensors are used. Insertion sensors are installed
into the existing pipe work through ball valves allowing the installation and removal of the entire sensor for repair, replacement,
or cleaning without dewatering the pipe.

The IS-6000 Doppler transmitter incorporates all the required algorithms and software for measurement accuracy and
repeatability. Parameterization of the measurement site, data logging, visualization and data transfer is possible by using the
browser-based control and management user interface, which can be run in any standard web browser via PC, notebook,
tablet or smart phone, regardless of location, time and operating system.
Applications:
Based on the pulsed wave Doppler principle, the flow measurement of IS-6000 Doppler meter requires suspended particles or
gas bubbles in the flowing liquid as reflectors of the acoustic signals. Therefore, the meter is ideally suited for continuous flow
monitoring in slightly to heavily polluted media.
• Wastewater treatment plants (influent measurement, real-time process control, effluent measurement)
• Wastewater collection systems (infiltration studies, hydraulic model calibration, event notification,
long term trend analysis)
• Urban drainage
