working principle

The flow profile of a flow sensor is similar to the profile of a Venturi tube. Place a set of spiral guide vanes on the inlet side, which force the fluid to generate intense vortex flow when it enters the flow sensor. When the fluid enters the diffusion section, the vortex flow is subjected to backflow and begins to undergo secondary rotation, forming a gyroscopic vortex precession phenomenon. The precession frequency is directly proportional to the flow rate and is not affected by the physical properties and density of the fluid. By measuring the secondary rotation precession frequency of the fluid with the detection element, good linearity can be obtained over a wide range of flow rates. The signal is amplified, filtered, shaped and converted into a pulse signal proportional to the flow rate by a preamplifier, and then sent to the microprocessor for integration processing along with temperature, pressure and other detection signals. After that, the measurement results (instantaneous flow rate, cumulative flow rate, temperature, pressure data) are displayed on the LCD screen.

main purpose

Widely used in industries such as petroleum, chemical, power, metallurgy, and urban gas supply to measure various gas flow rates, it is currently the most advanced product in oil field and urban natural gas transmission and distribution measurement and trade measurement.

feature

No mechanical movable parts, corrosion-resistant, stable and reliable, long service life, long-term operation without special maintenance

Using 16 bit computer chips, it has high integration, small size, good performance, and strong overall functionality

The intelligent flowmeter integrates a flow probe, microprocessor, pressure, and temperature sensors, and adopts a built-in combination to make the structure more compact. It can directly measure the flow rate, pressure, and temperature of the fluid, and automatically track compensation and compression factor correction in real time

The use of dual detection technology can effectively improve the strength of detection signals and suppress interference caused by pipeline vibration

Adopting a Chinese character dot matrix display screen with multiple digits, the reading is intuitive and convenient. It can directly display the volume flow rate under working conditions, the volume flow rate under standard conditions, the total amount, as well as parameters such as medium pressure and temperature

Using EEPROM technology, parameter settings are convenient, can be saved, and can store up to one year of historical data

The converter can output frequency pulses, 4-20mA analog signals, and has RS485 interface and HART protocol. It can be directly connected to a microcomputer and has a transmission distance of up to 1.2Km

In conjunction with our company's FM type data collector, remote data transmission can be achieved through the internet or network

Pressure and temperature signals are input to the transmitter, with strong interchangeability

The whole machine has low power consumption and can be powered by internal batteries or external power sources
