Krohne’s Waterflux is an electromagnetic flowmeter for applications in the field of water and wastewater. As a result, it is designed for custody transfer according to European Directive MI-001 and the measuring accuracy reflects the specifications of the ISO/EN, MI-001 and OIML standards. The adjustable operating frequency of 1 to 1/20 Hz guarantees reliable measurement results with rapid inflow and outflow rates.
Typical applications for the Waterflux include:
* Drinking water billing.
* Billing of ground water consumption for irrigation systems.
* Distribution network monitoring.
* Pipeline leakage detection systems.
* Water measurement in wells and transfer chambers.
Unobstructed pipe cross section
The true quality of a water meter lies in its measuring section, which determines whether the instrument can deliver precise, repeatable measurement results even in problematic applications such as suspended particles and solids in the water.
The unique design of the Waterflux, consisting of a rectangular cross section, optimised stainless steel electrodes and a homogeneous magnetic field, forms the basis for a flow-optimising pipe cross section and thereby provides reliable measurements that are largely independent of the flow profile.
The advantage is that Waterflux can measure flow bi-directionally. Also, users can customise the measuring frequency specifically to the application thus ensuring that the measurement results are always accurate, even when the flows are changing quickly.
The lining of the measuring tube is made of Rilsan, a material that is resistant to corrosion, ageing and abrasion. As a result, Waterflux is a food-grade flowmeter which complies with KTW, DVGW, WRc and NSF as well as ACS and is thus also approved for potable water.
Saving in installation and maintenance
Pricing is always an important criterion in the selection of a meter. Increasingly companies focus on the total cost of ownership including the purchase price, the costs of inaccuracy, under registration, and installation and maintenance costs. Typical mechanical meters have internal moving parts and are subject to wear and their performance deteriorates over time.
Electromagnetic water meters maintain their accuracy over time and due to their robust construction the time spent on routine maintenance and service activities can be reduced to a minimum. Being obstruction free also offers another important benefit as electromagnetic flowmeters cause only negligible pressure loss in the distribution network.
