flow measurement for full pipes
Allows high accurate flow measurement using the transit time method in full pipes. Up to 4 measurement paths.
The NivuFlow Mobile 600 was developed particularly for long-term measurements in field operation without external power supply.
Measurements for checking and verifying can be carried out with the self-sufficient and portable system without any problems even in harsh environments.
Battery lifetimes of several weeks or even months reduce personnel costs for maintenance and data readout significantly.

Transit Time – how the NivuFlow Mobile 600 measures
The NivuFlow Mobile 600 measurement principle is based on the detection of the transit time of ultrasonic signals between two sensors (A and B).
Here, the signal run time in flow direction t1 is shorter than the signal run time towards the flow direction t2. The difference between both run times is proportional to the average flow velocity along the measurement path vm. The NivuFlow Mobile 600 computes the average flow velocity vA from the measured path velocities vm.
The flow within the full pipe is calculated by utilising the general continuity equation:
Easy and convenient operation
The operation of the measurement system is password-protected by using a web browser installed on units such as smartphones, tablets or notebooks. Additional software or special apps are not required.
Since the transmitter can be used without the need to open the enclosure it is possible to operate the unit comfortably even under poor conditions or in bad weather. The connection to the unit is set up via WLAN.
Contactless or in the Medium
The transit time method based on ultrasound permits reliable and accurate measurements in clean and polluted media.
A wide selection of clamp-on sensors and wedge sensors as well as special pipe sensors is available. The system automatically detA key feature of the clamp-on sensors is the very quick installation since the sensors are installed on the outside of the pipe due the contactless measurement principle. Perfectly matched mounting accessories also enable the quick and easy installation of the medium-contacting sensors.
By connecting extra sensors it is possible to additionally measure process parameters such as pressure and temperature at the same time.
Your Benefits:
Tough Performer
The high protection degree of sensors and transmitters (IP68) permits use even under the harshest conditions. Even with its lid open the transmitter features IP 67 protection. The rechargeable batteries can be replaced also in wet environments such as during heavy rain.
Sophisticated Power Management
The NivuFlow Mobile 600 is designed for long-term operation and easiest handling. Equipped with two rechargeable battery packs the transmitter features a very long service life including simultaneous sensor power supply.
The rechargeable battery packs can be replaced by the user quick and easy on site to operate long-term measurements.
On Site from Anywhere
The measurement data can be transmitted via mobile phone network if necessary. The readings are transmitted to a web portal and can be then called up from anywhere in the world.
