Detailed Product Description: | QE600 Series thermal gas mass flow meter, thermal mass flowmeter of the thermal gas flowmeter principle the principle of thermal diffusion, thermal diffusion technology is the performance of an under harsh conditions, high reliability technology. The typical sensing element comprises two thermal resistors (platinum RTD), a speed sensor, one is automatically compensate for changes in the gas temperature of the temperature sensor. When the two RTD is placed in a medium, wherein the speed sensor is heated to a constant temperature above ambient temperature, and another temperature sensor for sensing the medium temperature. The gas mass flow flowing through the speed sensor is calculated by the amount of heat transfer to the sensor element. The gas flow rate increases, the increased medium heat taken away. The sensor temperature decreases. Must be increased in order to maintain a constant temperature, the current through the sensor, this part of the increase of the current size and the flow rate of the medium is proportional. , Thermal mass flowmeter Introduction: our gas flowmeter there rangeability small range below the lower limit of the basic flow is lost, however, this is unacceptable in some areas in gas trade settlement occasions endure the thermal gas mass flowmeter is a complete solution to this problem. Thermal gas mass flowmeter features the QE600 series thermal gas mass flow meter can gas flow metering, can also be used in the field of process control. The introduction of advanced U.S. technology to produce it without temperature and pressure compensation, the direct measurement of the mass flow rate of the fluid. Its salient features: no moving parts; pressure loss; range than the width; accuracy; reliability; simple to install, easy to operate. Comprehensive alternative to the orifice plate and differential pressure flowmeter in all areas. 2. Thermal mass flowmeter uses: This product is widely used in steel mills, coking plants, petroleum, chemical, thermal, medical, thermal power plants, environmental protection and other industries. : Steel plant, coking plant gas flow measurement boiler air flow, measuring the secondary air chimneys, flue gas flow measurement in water treatment the waterfall gas flow measurement cement, cigarette compressed air flow measurement of gas flow measurement, the glass factory in the production process of natural gas gas, liquefied petroleum gas, flare gas, hydrogen gas flow measurement, Technical parameters: Measuring range: (0.05 to 80) Nm / s (standard condition of 20 ℃, 101.33KPa) Measurements: Plug-tube struts temperature range: Ambient temperature: -40 ℃ ~ +60 ℃ medium temperature: -10 ℃ ~ +450 ℃ Accuracy: ± 1% of reading; ± 0.5% full scale Repeatability: ± 0.5% of full scale output :4-20mA DC ( maximum load 600Ω); RS232; The the RS485 response speed: <1S supply voltage: 24VDC ± 10% mechanical connection: 3/4NPT stainless steel fasteners (plug-in); flange probe length: 800mm (length plug-in standard length, special Please declaration) probe diameter: 18mm (plug-in) straight pipe length: pressure loss without strict requirements: You can ignore the working pressure: 1.6MPa; the 7.3 MPa site: LED display; LCD display data protection: Accumulated amount saved in EEROM, (power outage can be stored for centuries) sensor and pipeline table material: 316L (optional Hastelloy C) Protection: IP65 proof grade: ExdIICT4 four application examples. petrochemical industry applications: flare gas emissions Monitoring Advantages: Wide range ratio, the sensor is not easy to block, available online plug cleaning, widely applicable to gas power industry applications: boiler primary air, secondary air, coal grinding Wind wind measurement Advantages: easy to install, no straight pipe requirements, low pressure loss, no temperature and pressure compensation, can be used under harsh conditions (such as: air contains dust particles, wear serious, low pressure, etc.) 3. metallurgical industry applications: blast furnace gas, coke oven gas measurement Advantages: actual media component calibration, correct component changes, line cleaning sensor insertion length can be adjusted 4. electronics industry applications: high-purity gas mass flow measurement products advantages: direct measurement without temperature and pressure compensation mass flow sensor head highly polished, can be used for trade settlement 5. heating, ventilation and air conditioning systems (HVAC) Advantages: responsive, reliable operation, no strict requirements to install straight pipe 6 water treatment industry applications: measurement the aeration tank of air traffic Advantages: dirt, dust resistance, really no pressure drop, easy on-site installation 7 food industry applications: the reactor into the amount of gas, control the process and the quality of the product advantages: Sanitary 3A high purity, all wetted surfaces of stainless steel, wide turndown ratio |
