Page 3: Function And System Design
Proline Promag 50D Function and system design Measuring principle Following Faraday's law of magnetic induction, a voltage is induced in a conductor moving through a magnetic field. In the electromagnetic measuring principle, the flowing fluid is the moving conductor. The voltage induced is proportional to the flow velocity and is supplied to the amplifier by means of two measuring electrodes. -

Page 11: Operating Conditions: Installation
Proline Promag 50D Operating conditions: Installation Installation instructions Mounting location The sensor should preferably be installed in an ascending pipe. Ensure the sensor is an adequate distance (≥ 2 x DN) away from the next pipe bend. Note! Entrained air or gas bubble formation in the measuring tube can result in an increase in measuring errors. - Page 12 Proline Promag 50D Partially filled pipes Partially filled pipes with gradients necessitate a drain-type configuration. ³ 2 x DN ³ 5 x DN a0010707 Installation with partially filled pipes Down pipes Install a siphon or a vent valve downstream of the sensor in down pipes longer than 5 meters. This precaution is to avoid low pressure and the consequent risk of damage to the measuring tube.

Page 14: Adapters
Proline Promag 50D Adapters Suitable adapters to DIN EN 545 (double-flange reducers) can be used to install the sensor in larger-diameter pipes. The resultant increase in the rate of flow improves measuring accuracy with very slow-moving fluids. The nomogram shown here can be used to calculate the pressure loss caused by reducers and expanders. -

Proline Promag 50D Mounting kit The device is centered using the recesses on the sensor. Centering sleeves are also provided depending on the flange standard or the diameter of the pitch circle. Note! A mounting kit consisting of mounting bolts, seals, nuts and washers can be ordered separately (see "Accessories"). -
