DN 10...DN 50, DN 65 - Flow

The induQ® SIKA VMM65 magnetic inductive flow sensor is because of its robust design suitable for use in harsher ambient conditions. The steel fitting is entirely welded and therefore extremely stable and insensitive to interference. The available nominal diameters from DN 32 to DN 200 cover measurement requirements for average flow rates of up to 10 m/s. The large selection of high-quality materials provides for numerous application possibilities. Earth electrodes are available as an option. Besides, the SIKA VMM65 magnetic inductive flow sensor is available in both separate and compact design and is generally delivered with a calibration certificate. The electronic display allows customer-specific sensor configuration to meet the particular requirements on site. The smart flow sensors of the induQ® series operate according to the principle of induction: The measuring pipe is in a magnetic field (B). If an electrically conductive medium, with the flow (Q) to be measured, flows through the measuring pipe and thereby at a right-angle to the magnetic field, a voltage (U) is induced in the medium. This voltage is proportional to the average flow velocity and is picked up by two electrodes.

The SIKA VTR1010…1050 turbine flow sensor allows you to determine precisely, dependably and easily the flow rates of different liquids, such as water and other low viscosity liquids, under the most severe conditions. The SIKA VTR1010…1050 sensor is particularly robust and, due to the wide range of nominal diameters and five different pick-ups, can cope with even the most severe conditions. The characteristic variable is the K-factor (pulses per litre) which is specific to each measuring unit, is determined by calibration and specified on the nameplate. A five-point calibration report can be supplied on request. The VTR sensor consists of the measuring turbine and a pick-up mounted on the outside. The liquid flows into the measuring turbine and causes the rotor to move. Due to the characteristic internal diameter, the speed of rotation is directly proportional to the flow rate. The moving rotor blades are detected by the pick-up and this is converted into a pulsed signal proportional to the flow rate.
