The ultrasonic pulses are emitted by two clamp-on sensors installed on a clear PVC pipe. Recommended learning material, also order: “Ultrasonic Flow Transmitter” → Page 165 Order no. 588330 2 Electromagnetic Flow Transmitter Device that relies on the conductive properties of liquids traveling across a magnetic field to measure the flow in a pipe. It is insensitive to vibrations and causes almost no pressure loss. Temperature variations of the fluid are automatically compensated by the device for accurate flow rate measurement. The variant “transmitter on the left” must be used if the transmitter is to be installed on the second team side of the Process Workstation. Recommended learning material, also order: “Electromagnetic Flow Meters” → Page 164 Transmitter on the right HART 582413 Ethernet 588319 WLAN, Heartbeat 611542 Transmitter on the left HART 582419 Ethernet 582418 WLAN, Heartbeat 8184574 3 Paddle Wheel Flow Transmitter Device that provides an accurate measurement of the flow rate by inserting a paddle wheel into the flow stream. A sensor measures the velocity of the paddle wheel which is converted into a direct reading of the flow rate displayed on a remote digital display. Also features a 4 – 20 mA output signal. Recommended learning material, also order: “Paddle Wheel Flow Transmitter” → Page 165 Order no. 588326 4 Vortex Flow Transmitter Device that uses the dynamic properties of fluids to create small vortexes whose frequency of detection is proportional to the flow in a pipe. This device is typically used in the industry to measure the flow of high or low temperature fluids. Recommended learning material, sold separately: “Vortex Flow Transmitter” → Page 164 Hart 588320 Hart, Heartbeat 611543 5 Coriolis Flow Transmitter Flow measurement device that uses the Coriolis forces generated when a fluid goes through the flow meter to measure the mass flow of liquid in a pipe. Since it measures the mass flow, the measurement is not affected by changes in the temperature, viscosity, and density of the fluid. Recommended learning material, also order: “Coriolis Flow Transmitter” → Page 164 HART 588323 WLAN, Heartbeat 611540 6 Pitot Tube Flow measurement device relying on a small tube inserted in the flow stream to measure the dynamic pressure of a fluid from which the flow rate can be inferred. It presents a low pressure-loss and clearly illustrates the working principles of such a device. It requires the use of a differential-pressure transmitter to transform the pressure drop into a usable flowrate value. Recommended learning material, also order: “Flow Primary Elements” → Page 163 Order no. 588316 7 Picomag Electromagnetic Flow Meter Magnetic-inductive flow meter Picomag. Operation and maintenance via the SmartBlue app. Recommended learning material, also order: “Electromagnetic Flow Meters” → Page 164 Bluetooth, IO-Link 611547 4 5 6 1 2 3 7
