RS Hydro has recently won a contract to supply and install various flow meters for the measurement of sludge with very high solid content on an industrial application within the UK. Field engineers attended site and concluded that the Nivus OCM EM and Siemens 911/E would be the most suitable flow metering equipment.
The 911/E Siemens electromagnetic flow meter is especially suited to the measurement of slurries. The power behind the Sitrans 911/E means that it is ideal for flow velocities up to 12m/s, and the minimum conductivity required is just 0.01?S/cm with a pulsed alternating field of 3?S/cm with a pulsed constant field. This rests upon Faraday's Law of Induction, in which an electric voltage is induced in a conductor moving through a magnetic field.
The complete flow meter is comprised of the flow sensor and the corresponding transmitter. In this application, RS Hydro selected the TransMag 2 Remote Version for the benefits of its 16-bit microprocessor-based transmitter with alphanumeric display; automatic recognition; and simple menu operation.
These sophisticated yet user-friendly flowmeters will be installed alongside the Nivus OCM EM. This is a flexible flowmeter, which can be used on pipes or open channels to measure depth, velocity and flow. In this instance the pipes are partially full and open-ended so the OCM EM is a sound choice. It is reliable and can work continuously in sanitary, storm sewers or open channels. This dependability and adaptability make the Nivus OCM EM an ideal flow meter for such an effluent discharge application. The flow meters will all be above ground and so the use of vandal-resistant bollards ensures that the equipment is protected from damage.
The use of these two very different flow measurement technologies with vandal resistant protection reaffirms RS Hydro's position as a major player in effluent flow measurement, and as a provider of total solutions.
