Detailed Product Description: | Smart Swirlmeter is my factory developed with leading domestic level of new gas flow meter. Set the meter flow, temperature, pressure detection functions, and can be temperature, pressure, compressibility factor automatic compensation, is an ideal instrument petroleum, chemical, power, metallurgy and other industries for gas measurement. 1.1 Main features no mechanical moving parts and difficult to corrosion, reliable, long life, long-term operation without special maintenance; using 16 computer chips, high integration, small size, good performance, the whole function is strong; smart meter Set flow probe, microprocessor, pressure, temperature sensors in one, take a built-in combination, make the structure more compact, direct measurement of fluid flow, pressure and temperature and automatically compensate for real-time tracking and compression factor correction; website: www. jyllj.com double-detection technology can effectively improve the detection signal strength and interference suppression of vibration caused by pipeline; leading domestic intelligence seismic technology effectively suppresses interfering signals caused by vibration and pressure fluctuations; the use of Chinese characters dot matrix display screen display digits and more intuitive readings, displays the work of state volume flow, volume flow under standard conditions, the total amount, as well as media pressure, temperature and other parameters directly; using EEPROM technology, convenient parameter settings can be permanently stored and can save up to one year of historical data; converter output frequency pulse, 4 ~ 20mA analog signals, and has RS485 interface for direct interconnection with the computer, the transmission distance of up to 1.2km; more physical parameters alarm output, Users can optionally one; meter meter can be rotated 360 degrees, easy to install and use; with the company's FM-type data logger for remote data transmission via the Internet or telephone network pressure, temperature sensor input signal interchangeable; low power consumption machine, available battery-powered, can also be an external power supply. 1.2 The main purpose intelligent Swirlmeter can be widely used in petroleum, chemical, power, metallurgy, city gas and other industries to measure a variety of gas flow, is the product of choice for oil and city gas distribution measurement and trade measurement. Second, the structure and working principle of the meter by 2.1 meter structure following seven basic components (Figure 1): 1. bluff body made of aluminum alloy, with a certain angle helical blade, it is fixed at the front of the housing contraction section Ministry, forcing fluid to produce a strong vortex flow. ⒉ case itself with a flange, and a certain form of fluid channels, depending on the operating pressure, the housing material can be cast aluminum or stainless steel. (Figure 1) ⒊ smart meter Totalizer (schematic shown in Figure 3) by the temperature, pressure testing analog channels, digital channels and traffic detection micro processing unit, a liquid crystal driver circuit and other auxiliary circuits, and with external input signal interface . 4. In Pt100 platinum resistance temperature sensor for temperature sensitive element, at a certain temperature range, its resistance to temperature corresponding relationship. 5. Pressure sensors diffused silicon piezoresistive bridge is sensitive element, which is expected to arm the resistance will change under external pressure, so in a certain role in the excitation current, the potential difference between the external pressure is proportional to its two outputs . 6. The piezoelectric crystal sensor is mounted in the housing near the throat section of the expansion, can be detected vortex precession frequency signal. ⒎ racemic outlet section is fixed in the housing, and its role is to eliminate the swirling flow, to reduce the impact on the performance of downstream meter. 2.2 Circulation sectional flow sensor works similar venturi-type line (Fig. 2). Placed at the inlet side of a group of helical guide vanes, when the fluid enters the flow sensor, the guide vanes forcing fluid generating intense swirling flow. When the fluid enters the diffuser, vortex flow by the effect of reflux, begin to make the second rotation of the vortex formation gyro precession phenomenon. The impact of the precession frequency is proportional to the size of the flow, from the fluid physical properties and density of the fluid sensing element measured secondary rotation precession frequency can get good linearity over a wide flow range. Signal by the pre-amplifier, filtering, shaping converted to velocity proportional to the pulse signal, and then the temperature and pressure detection signal is sent to the microprocessor Totalizer together, at last showing on the LCD screen measuring The results (instantaneous flow, cumulative flow and temperature, pressure data) |
