Proline Promag 50W, 53W Function and system design Measuring principle Faraday’s law of induction states that a voltage is induced in a conductor moving in a magnetic field. In electromagnetic measuring, the flowing medium corresponds to the moving conductor. The induced voltage is proportional to the flow velocity and is detected by two measuring electrodes and transmitted to the amplifier. Flow volume is computed on the basis of the pipe's diameter.

Proline Promag 50W, 53W Metal, ungrounded piping In order to prevent outside influences on measurement, it is advisable to use ground cables to connect each sensor flange to its corresponding pipe flange and ground the flanges. Connect the transmitter or sensor connection housing, as applicable, to ground potential means of the ground terminal provided for the purpose. Caution! Also, observe company-internal grounding guidelines.
PAGE 12
Proline Promag 50W, 53W Plastic pipes and isolating lined pipes Normally, potential is matched using the reference electrodes in the measuring tube. However, in exceptional cases it is possible that, due to the grounding plan of a system, large matching currents flow over the reference electrodes. This can lead to destruction of the sensor, e.g. through electrochemical decomposition of the electrodes. In such cases, e.g.

Proline Promag 50W, 53W Operating conditions Installation conditions Installation instructions Mounting location Correct measuring is possible only if the pipe is full. Avoid the following locations: • Highest point of a pipeline. Risk of air accumulating • Directly upstream of a free pipe outlet in a vertical pipe. F06-5xxxxxxx-11-00-00-xx-000 Installation of pumps Do not install the sensor on the intake side of a pump.

Proline Promag 50W, 53W Partially filled pipes Partially filled pipes with gradients necessitate a drain-type configuration. The Empty Pipe Detection (EPD) function offers additional protection by detecting empty or partially filled pipes. Caution! Risk of solids accumulating. Do not install the sensor at the lowest point in the drain. It is advisable to install a cleaning valve.
PAGE 16
Proline Promag 50W, 53W Orientation An optimum orientation helps avoid gas and air accumulations and deposits in the measuring tube. Promag, nevertheless, supplies a range of options and accessories for correct measuring of problematic mediums: • Electrode Cleaning Circuitry (ECC) to remove electrically conductive deposits in the measuring tube, e.g. in accretive mediums.

Proline Promag 50W, 53W Vibrations Secure the piping and the sensor if vibration is severe. Caution! It is advisable to install sensor and transmitter separately if vibration is excessively severe. Information on resistance to vibration and shock can be found on page 20. > 10 m F06-5xxxxxxx-11-00-00-xx-006 Foundations, supports If the nominal diameter is DN ≥ 350, mount the transmitter on a foundation of adequate load-bearing strength. Caution! Do not allow the casing to take the weight of the sensor.

Proline Promag 50W, 53W Limiting flow The diameter of the pipe and the flow rate determine the nominal diameter of the sensor. The optimum velocity of flow is 2...3 m/s. The velocity of flow (v), moreover, has to be matched to the physical properties of the medium: • v < 2 m/s: for abrasive mediums such as potter’s clay, lime milk, ore slurry, etc. • v > 2 m/s: for accretive mediums such as wastewater sludge, etc.
