  • Page 8: Applications

    Waterworks Sensors APPLICATIONS The sensors manufactured by the company EUROMAG are widely used in many applications where it is important to measure the flow rate of electrically conductive liquids. Various models can be used in different applications. The table below shows the typical applications according to the individual sensor models manufactured by EUROMAG.
  • Page 9: Product Description

    Waterworks Sensors PRODUCT DESCRIPTION OPERATING PRINCIPLE The electromagnetic sensor is used to measure the flow rate of liquids (drinking water, wastewater, beverages, fertilizers, chemical products, and any other liquid) that have an electrical conductivity of at least 5μS/cm. Electromagnetic flowmeters are the best solution for measuring the flow rate liquids because of fast response times, great measurement accuracy, and a passage tube that does not present any obstruction to the liquid flow, therefore no pressure drop in the pipe.

    Waterworks Sensors 3.4.4 Underground installations The remote sensor is protected by IP68/ NEMA 6P and can be positioned underground. We recommend the use of gravel for at least 300mm (12 inches) around the sensor. This provides drainage and prevents dirt solidification on the sensor.
  • Page 23: How To Avoid Air Pockets In The Pipelines

    Waterworks Sensors HOW TO AVOID AIR POCKETS IN THE PIPELINES This paragraph is intended to help the designers and users of electromagnetic flowmeters to create the best installation layout that guarantees optimum performance of the meter, taking into particular consideration the problem of the presence of air pockets in the pipe.
  • Page 24 Waterworks Sensors Fig. 37 Air pockets inside the pipe The greater the diameter of the pipe, the higher the speed of the liquid will be required to move the air pockets away from the flowmeter. It is also important to understand what kind of effect the water pressure has on the nature of the air pocket inside the pipe.
  • Page 25 Waterworks Sensors A minimum slope in an ascending flow of 1: 500 or higher is recommended in order to stimulate the entrapped air pocket to move away from the meter. Drawings are made with an exaggerated slope for greater clarity Fig.
  • Page 26 Waterworks Sensors The design of the vent valve is essential to ensure that the entrapped air pockets are released. Pneumatic valves or vacuum switches should be avoided. Instead, it is preferable to use combined pneumatic valves that incorporate an automatic orifice, as well as a large kinetic orifice. These valves ensure that the largest volumes of air are released quickly and effectively while filling the pipe.
