ZRN-LW-A turbine flow sensor
| I. Overview|
ZRN-LW-A turbine flow sensor and display instrument composed of turbine flowmeter sensor with high accuracy, good repeatability, simple operation, long life and other characteristics can be widely used in the volume of petroleum, chemical, metallurgy, paper and other industries measure liquids instantaneous flow rate and total volume. ZRN-LW intelligent electronic turbine flow meter (hereinafter referred to as the meter) is a new mechatronic intelligent velocity flowmeter. is our patent product. for the domestic original, it absorbs the traditional rate formula Single-velocity flow meter flowmeter features, innovative structure, improve the accuracy. and through the computer system internal error correction, so that accurate measurement reaches 0.5, and live online calibration. Features The meter is a simple structure, strong durable, easy to install and maintain, no jam. And the work of the media do not ask, oil, gas, sand, mud, and the mixture can still be completely normal. The attendance figures show the cumulative and instantaneous flow, intuitively clear and accurate. and can be cleared zero with standard communication interface Far EasTone secondary display. remote pulse and two current output. There are self-powered. No external power supply can be used. Strong anti-jamming capability of the meter in a high electric field, high Working under a magnetic field normal proof mark IaIICT4, flameproof flag Diibt4, protective:. IP68, suitable for all kinds of places.
Second, the principle
The speed turbine flowmeter is a single flow rate meter, as I plant unique patented product, the structure of a single impeller hanging in the pipeline side, pushing its rotation by the liquid, the sensor is converted into an electrical signal, after the amplifier away transfer out. calculated flow value can be obtained.
Third, the environmental conditions
Ambient temperature: -40 ~ + 80 ℃ external magnetic field ≤400A / m
• pressure loss is small, the impeller prevent corrosion.
• has a high resistance to electromagnetic interference and vibration resistance, long operating life and reliable performance.
• The use of advanced ultra-low-power single-chip microprocessor technology, machine function, low power consumption, superior performance. Intelligent traffic with non-linear precision compensation function display
Is Fixed formula accuracy of better than ± 0.02%.
• meter factor can be the key online settings, and displayed on the LCD screen, LCD screen, intuitive and clear, high reliability.
• using EEPROM cumulative flow meter factor power-down protection. Protection longer than 10 years.
Fourth, the main technical parameters:
• The flowmeter specifications, basic parameters and performance indicators
• Accuracy: 0.5, 1.0;
• Conditions of Use:
1, ambient temperature -20 ℃ ~ 50 ℃;
