Shanghai Yinuo Instrument Co.,Ltd

LTD Serials general electron flowmeter (hereafter call flowmeter), is a precise flowmeter measuring the flow of liquid in the tube. This flowmeter is a patent right product, which is independent researched and developed by the technicians of our company based on innovation and improvement to foreign latest advanced technology. It has the characteristic of high accuracy measuring, compact size, wide flow range, strong anti-jammed, sandsproof, anti-jammed, high-temperature, resistance, anti-corrosive, low power consumer, local LCD display, far transmit. It is widely used in petroleum, chemistry, metallurgy, light industry, especially applied in measurement of watery oil in oil field and measurement of low-viscidity sewage, finished oil and edible oil. The flowmeter is composed of four parts: body, core, sensor, meter head. The core is easily taken out from body, which is very convenient to the periodical maintenance. Applied with advanced electron technology and particular design, it remains high stability and anti-disturbance. It can be applied in explosion situation with the anti-explosion grade of EXd?BT4. For local display, this flowmeter is charged by inner lithium buttery, which can work continuously for three years.

1.High Accuracy, Large Turndown Ratio
2.Anti-High Temperature and Erode
3.Anti-impurity;
4.Well Interchange
5.Local instant flow and total flow LCD display,distant signal transmission;
6.Best Measured Fluid:Water, waste water, low viscosity oil,etc.

When the liquid flows through the flowmeter, it push the wheel running. Within a certain flow range, the circling speed of wheel is direct proportion 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 which resulting 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 show separately instant and totalizer flow.
