In-line flow measurement system in open or closed pipes and channels

Reliable flow measuring system for flow velocity and fill level. The flow measuring system enables flow measurement in turbid and aggressive liquids and is suitable for applications in Ex and non-Ex areas.

In-line flow measurement system in open or closed pipes and channels

Ultrasonic flow sensor for (waste) water and industrial waters

The flow measurement system enables flow measurement in cloudy and aggressive liquids and is suitable for applications in Ex and non-Ex areas. The ATEX certified measuring system consists of the DSM-2420 flow meter and the FDL400 data logger or Ex power supply unit SG2420.

The sensor is installed in partially or completely filled pipes and channels and delivers reliable measurement results from fill levels of just 3cm. The flow velocity is recorded using an ultrasonic measuring principle (Doppler effect), and the fill level is determined hydrostatically.

The measurement signals are evaluated using the compatible data logger or can be integrated into other existing measurement, alarm and control systems. The data logger (FDL400) saves the measured values ​​on an SD card and also enables the flow rate to be calculated and limit values ​​to be monitored.

The robust measuring system is suitable for flow measurement for all types of turbid, aggressive and non-aggressive liquids in the water and wastewater industry, as well as in industrial wastewater networks (beverage production, process water). The measurement is carried out in-line and flexibly in standardized and individual pipe and channel geometries.

Continuous in-line flow measurement: Your advantages as a system operator

• Optimization in the planning or operation of your sewer network

• Support for efficient system operation

• Sensor-based control of systems and processes in water management

• Increased environmental protection

• Ideal for self-monitoring of wastewater systems

• Easy installation in existing sewer structures without any on-site measures
