Description of DDTOP LWGY

LWGY series turbine flowmeter is a new generation flowmeter which has absorbed advanced international technology of flow instrumentation. After optimized design, it has the features of simple structure, light weight, high precision, good reproducibility, responsiveness, easy installation and maintenance, etc. Turbine flowmeter is a precision flow measurement instrument to measure the flow and total volume of liquid without impurities and corrosion. It is widely used in petroleum, chemical, metallurgical, scientific research and other fields.

Features
• High accuracy: generally up to ±1%R, ±0.5%R, high precision type up to ±0.2%R.
• Good repeatability, with short-term repeatability of 0.05% R to 0.2%R, which makes it the preferred flow meter in trade settlements, precisely because of its good repeatability, such as frequent or on-line calibration for high accuracy.
• Output pulse frequency signal, suitable for total volume measurement and computer connection, no zero drift, strong anti-interference ability.
• Very high frequency signals (3-4 KHz) can be obtained, with strong signal separation rates.
• Wide range, up to 1:20 for medium and large sizes and 1:10 for small sizes.
• Compact and lightweight, easy to install and maintain, with high circulation capacity.
• Suitable for high-pressure measurement, no holes are required on the meter body, and it is easy to make a high-pressure meter • There are many types of special sensors, which can be designed according to the special needs of users, such as low temperature type, two-way type, down hole type, special type for sand mixing;
• It can be made into a plug-in type, suitable for large size measurement, with low pressure loss, low price, continuous flow out, easy installation and maintenance.

Operating Principle
When the measured liquid flows through the sensor type, under the action of the fluid, the blade rotates under force, and its speed is proportional to the average flow velocity of the pipeline. The rotation of the blade periodically changes the magnetic resistance value of the magnetic circuit, and the periodic change of the magnetic flux resistance in the detection coil generates an induced electromotive force with the same frequency as the blade rotation frequency, which is amplified, converted and processed.

Applications

  • Crude Oil Treatment: Metering Station
  • Chemical: Chemical Injection, Desalted Water Tank

Notes:

  1. The maximum pressure loss is the pressure loss when the flowmeter works at the maximum flow point. The medium is water, and the temperature is normal.
  2. Products with an accuracy level of ±0.2% need to be customized, and the flow range is smaller than the conventional range.
