The main ways to connect electromagnetic flowmeters to pipelines are flange connection, clamp connection, sanitary connection, and threaded connection. Below, the relevant staff from Jiangsu Hengda Instruments will give you a brief introduction to these methods. 1. Hygienic connection: The small-diameter hygienic electromagnetic flowmeters produced by Jiangsu Evergrande Instruments use a hygienic connection method, namely a clamp-type connection. This approach allows for connection to IDF fittings established by the International Dairy Federation, enabling quick disassembly and installation as well as facilitating frequent cleaning on a daily basis. 2. Threaded connection Small-diameter electromagnetic flowmeters also use a threaded connection method. Such instruments are widely used in industries such as pharmaceuticals and food, as well as in applications involving the precise mixing and injection of substances in the pharmaceutical sector. Threaded connections are also widely used in industries such as petroleum and geological exploration for measuring the flow rate of high-pressure water injection or cement slurry at pressures above 16–25 MPa, with a trapezoidal thread shape. 3. Flange connection The flange connection is a traditional method of connection; the sensor of an electromagnetic flowmeter has connection flanges at both ends, which are secured to the pipe flanges using bolts, allowing for installation in one direction only. The sensors of large-diameter electromagnetic flowmeters produced by Jiangsu Evergrande Instrument Technology use this type of connection. It is larger in both volume and weight than the clamped connection. The length between the two flange faces of DN15～600mm electromagnetic flowmeters has been standardized by the International Organization for Standardization (ISO13359;1998) to ensure consistency. 4. Clamping connection The clamping connection is a type of connection that has been developed in recent years. The sensor of an electromagnetic flowmeter does not have flanges, and it is held between the flanges of the pipeline using long bolts in order to be integrated into the piping system. Sensors using this connection method are small in size and light in weight, and they exhibit strong adaptability to different pressure specifications as well as various flange hole spacings in piping systems ； But it is only applicable to smaller pipe diameters (below DN200mm) with lower working pressure from the fluid.
