LTD Serials General Electron Flowmeter (hereafter call flowmeter), is a precise flowmeter to measure the flow of liquid in the tube.
Feature
1.High Accuracy, Large Turndown RatioÂ
2.Anti-High Temperature and Erosion-proof
3.Anti-impurity 4.Well Interchange
5.Local instant flow and total flow LCD display, distant signal transmission;
6.Measurable medium: Water, waste water, low viscosity oil, etc.
Principle
When the liquid flows through the flowmeter, it pushes the wheel running. Within a certain flow range, the circling speed of wheel is direct proportional to the volume of the flow. When wheel running, the magnetic stainless slice of wheel will approach the loop of sensor and periodically change resistance of loop to result the emerge of impulse signal which is direct proportional with volume at the moment through the change of amount of loop's magnetism. This signal, after analyzed and amplified, will display instant and total flow separately.
