Collection of planning data Basic data for billing networks Verification of existing measuring facilities Precipitation discharge measurement Investigation of extraneous water Throttle calibration PCM – without compromises in practice in order to assess the hydraulic conditions of sewer networks and associated special constructions it is an indispensable prerequisite to carry out measurements within the network. This is why the use of portable and mains-independent flow measurement instruments for the detection of extraneous water, channel efficiency, sewerage master planning or influent control...

A measurement system for portable flow measurements basically consists of a transmitter Type PCM for power supply, data entry, indication and data storage plus a sensor for the recording of measurement data. Sensor construction as well as the built-in pickups may be customized individually according to the conditions prevailing on site. NIVUS flow measurement stands for innovation und highest accuracy. The portableType PCM units are designed for use in part filled and full channels, pipes and flumes with various shapes and dimensions. Many communication options and comprehensive extension possibilities...

The Flow Measurement Principle Flow cannot be measured directly. Multiple factors are required to detect the flow Q: average flow velocity and the flow cross section. This leads to the general formula below: Q = v(average) • A The flow cross section A is investigated by continuously measuring the filling level considering the channel shape.The flow cross section and hence the flow changes as soon as the level changes. The NivuCompact can be connected to the PCM directly The flow velocity is detected via the velocity of the particles. Most media contain a certain load of dirt particles or gas...

The measurement method used for flow velocity investigation is based on the principle of ultrasonic reflection. One of the most modern and most efficient methods for the detection and calculation of the flow velocity is the correlation method (interrelation between two similar image patterns) by NIVUS. A prerequisite to use this method are reflecting particles (minerals or gas bubbles) contained in the medium. Existing reflectors (particles, minerals or gas bubbles) are scanned using an ultrasonic impulse with a defined angle. The resulting echoes are saved subsequently as images or echo patterns....

The Type "Mini" sensor family provides the best possible measurement system to detect lowest discharges e.g. for measurement of extraneous water or indirect discharge measurements. The sensors use our patented and proven ultrasonic cross correlation method. This method allows to detect and to indicate flow profiles starting at levels of only a few centimeters. The sensor construction is particularly suitable for small dimensions and reduces backwater effects, the risk of build-up or blockage. You can find comprehensive specifications in the respective manuals or on www.nivus.com
