Insertion Emag meters

Compact Pluggable Insertion Magmeters
  • Compact Pluggable Insertion Magmeters
  • Remote Pluggable Insertion Magmeters
  • Compact Fixed Depth Insertion Emag meters

The RBEF-I Insertion Electromagnetic flow meter（Emag meters） can be installed in any pipeline of internal diameter from 50mm (2in) to 8000mm (360in) through a small tapping.

The RBEF flow meters are ideal for use in process measurement and control, survey, leak detection, etc. applications such as leakage monitoring, and network analysis and in permanent locations where cost or space limitations preclude the use of conventional closed pipe meters.

RBEF-I Insertion Electromagnetic flow meter types:

  • Fixed-depth Insertion Electromagnetic flow meter
  • Pluggable Insertion Electromagnetic flow meter(Magflow)
  • Blind(without display) Insertion Magnetic flow meters
  • Compact and Remote type Insertion Magnetic flow meter

Principle

Principle of Operation

Faraday’s law of electromagnetic induction states that an inductive voltage is generated when a conductor moves through a magnetic field. This principle is used as the basis of flow measurement in the RBEF-I electromagnetic flow meter.  In the electromagnetic flow meter, the flowing fluid corresponds to the moving conductor as described in Faraday’s law.

UE ∞ B * D * v

The induced voltage UE is directly proportional to magnetic field intensity (B), electrode spacing (D) and average fluid velocity (v). Since magnetic field intensity (B) and the electrode spacing (D) are constant values, induced voltage UE is therefore directly proportional to the average flow velocity (v).

Q = (∏ * D2) / 4 * v     therefore    UE ∞ Q

The equation for calculating volumetric flow rate (Q) shows that the induced voltage (UE) is linear and directly proportional to the average velocity (v).  In the flow meter transmitter, the induced voltage (UE) from the electrodes is used to calculate volumetric flow rate (Q) based upon the pipe’s internal diameter.

UE = Induced voltage

B = Magnetic field strength

V = Fluid velocity

Q = Instantaneous volumetric flow rate
