Nivus has equipped the NivuFlow series units with the option of cycle or interval operation. This, according to the manufacturer and supplier of measurement systems, allows “large part” of the energy consumption to be reduced compared to continuous operation. Operators of permanently operated measurement places without a connection to mains power will be able to benefit from the option of energy-saving operation, as the self-sufficient power supply can be made smaller in terms of dimensioning and effort.
With a measurement interval of 15 minutes, more than 90% of the energy is saved compared to continuous measurement. This makes solar cells or wind generators and buffer batteries smaller in size and also suitable as an energy source for flow measurements in Europe. In the case of using fuel cells, maintenance trips of refuelling are reduced to one-tenth compared to continuous operation, Nivus claimed.
In conjunction with the integrated NIVUS Connectivity, which the devices provide on request, the operator can call up the measurement data from the workplace or on the road. This reduces journeys to the measuring point to a minimum.
For some events, such as when a certain level is exceeded, the measurement system switches to event operation. This allows shorter individually adjustable measuring cycles or continuous operation. The operator thus has the possibility to generate high-resolution measurement data in case of critical events. This provides a database for measurement data analysis.
For older devices of the NivuFlow series, Nivus also offers the option of interval operation by means of a firmware update.
Typical applications are self-sufficient flow measurements for rainwater overflows, transfer measuring points in the sewer network, measurements in rivers and irrigation systems.
