Positive displacement Roots Flowmeter for natural gas
KKQY series gas waist wheel flowmeter is based on the principle of volumetric measurement to accurately measure the gas flow meter.The instrument has the characteristics of high precision, high reliability, wide range and high performance.This series of flowmeters are widely used in: city pipeline gas metering, industrial gas metering, gas regulator station metering, energy management and other non-corrosive gas metering live flow control and other occasions.Product performance up to the domestic advanced level.
The intelligent gas waist wheel flowmeter is mainly composed of shell, conjugate rotor and intelligent flow integrator.A pair of conjugate rotors installed in the metering chamber maintain the correct relative position of the rotor through fine-machined adjusting gears under the action of the inlet and outlet pressure difference of the circulating gas .Keep the best working clearance between rotor, between rotor and shell, between rotor and wallboard, realize the continuous non-contact seal.Each rotation of the rotor, the output of four times the effective volume of the metering chamber of gas,The rotor revolution is transmitted to the intelligent flow integrator through the magnetic seal coupling device and deceleration mechanism, so as to display the cumulative volume of the output gas.
According to the principle of electromagnetic induction, using the weigen sensor from the synchronous rotation gear installed on the opposite magnetic steel magnetic induction flow volume flow proportional to the pulse signal,After amplification, filtering and shaping, the signal enters the micro-processing unit of the intelligent flow integrator together with the temperature and pressure sensor signals for calculation and processing, and displays the volume flow and total amount of gas directly on the LCD screen.The rotating shaft can also be displayed on the mechanical disk according to the magnetic drive through the gear set to form a mechanical count.
- Strict material selection of internal rotor, uniform density and special treatment,Strict material selection of internal rotor, uniform density and special treatment
- The flow meter does not need straight pipe section before and after, can be installed in a narrow range, easy to use.
- The lower starting flow , the widely range ratio , and the maximum range ratio is up to 1:300,suitable for a variety of operating conditions.
- Pressure sensor, temperature sensor and flow sensor are all built in, making the structure more compact and less volume.
- Using advanced microcomputer EPT and high-performance integrated chip,The machine has powerful functions and superior performance,The power consumption of the whole machine is low, which means that it can run with the built-in battery for a long time, and can also be transmitted to other devices through pulse signa outputl, 4~20mA output.And it has RS -485 communication function to transmit instrument information through wireless network, local area network and other means.
- The integrator is designed with functions of lightning protection and surge prevention.And a multi – memory point backup function to protect user information safe and reliable.
- Adopt special bearing for flow meter imported from Germany,Large screen display,multidisplay,Clear, and intuitive data,reading is convenient,Real-time display of temperature and pressure,Real-time measurement.
- Electronic counting, mechanical counting and other methods can be selected ,Compliance with international standards.
- Unexpected power failure, data permanent storage, prevent data loss.
- Special structure is designed to prevent external magnetic and EPT interference from affecting metering.
