Design and Manufacturing according to CE Standard
Magnetic Liquid Flow Meter with Relay Switch for Milk, Water (Ex Approved)
Introduction
TFL55 Magnetic Flow Meter Series are fit for the measurement of liquid in pipes. The advantage is it can be installed from any direction, neglecting the influence of liquid. TF55 Series can display current flow rate of volume and mass.
With its special design,TFL55 Series is suitable for the measurement of liquid medium which flowing stably without caking and sedimentation.
TFL55 Magnetic Flow Meter Series is your best choice of process controlling instrument under bad condition.
Feature

· Multi to installation Type: vertical and horizontal
· Wide range of application
· Wide Measuring Range
· Easy Display
· Available for Flow Control, Monitoring, 4 to 20mA, 2 to wired
Measureing Principle
The rotational direction of the paddle alters along the axis when the paddle is pushed by the flowing media until the pushing force equal to the reacting force of the paddle plus the tension force of the spring. The angular position of the paddle or balance position of the paddle indicates the flow of the media.
Processed by the Permanent magnetic inductor, the movement of the pointer is driven by the Magnetic Coupling Servo System. Meanwhile, the flow value is display on the dial and is transmitted to the electrical converter.
This measuring principle is of high reliability and safety. The value shown is valid for the calibrated media or media with similar physical properties.
