1. Flow range of steam vortex flowmeter
Code: Tongrentqi radial flow range ㎡/h OW-LU-25 DN25 1~10 (liquid) 25~60 (gas) Steam flow rate Please refer to the instruction manual of Yiyanling for details, For DN300 and above, it is recommended to use the plug-in vortex flowmeter OW-LU-32 DN32 1.5~18 (liquid) 15~150 (gas) OW-LU-40 DN40 2.2~27 (liquid) 22.6~150 (gas) OW-LU-50 DN50 4~55 (liquid) 35~350 (gas) OW-LU-80 DN80 9~135 (liquid) 90~900 (gas) OWLU-100 DN100 14~200 (liquid) 140~1400 (gas) OW-LU-150 DN150 32~480 (liquid) 300~3000 (gas) OW-LU-200 DN200 56~800 (liquid) 550~5500 (gas)
2. What is used to measure condensate flow rate?The measurement of condensate flow mainly adopts three methods: electromagnetic flowmeter, vortex flowmeter, and ultrasonic flowmeter Electromagnetic flowmeter • Principle: Based on Faradays law of electromagnetic induction, suitable for conductive liquids (condensate water conductivity is usually qualified) • Accuracy: ± 0.5%~± 1.0% (DN15-DN300 pipe diameter) • Advantages: No pressure loss, corrosion resistance, suitable for high temperature and high pressure environments (up to 180 ℃/4MPa) • Vortex flowmeter • Principle: Flow rate is calculated by detecting the Karman vortex frequency • Accuracy: ± 1.0%~± 1.5% (ensuring that the straight pipe section is ≥ 20D) • Note: Not suitable for low flow rate (＜ 0.5m/s) working conditions, vibration environment requires the installation of shock absorbers 3 Ultrasonic flowmeter • Type: Time difference type (accuracy ± 1%) or Doppler type (applicable when impurities are included) • Installation: External clamp type does not require pipe breakage, but requires pipe wall bending thickness<15mm and no serious scaling.

3. There are multiple types of DN300mm caliber flow meters
3. There are multiple types of DN300mm caliber flow meters
There is a significant difference in weight between different DN300mm caliber flow meters, with electromagnetic flow meters (100-200kg)>ultrasonic pipe section flow meters (50-150kg)>vortex flow meters (30-80kg)>external clamp ultrasonic flow meters (<10kg).
. After understanding the application scenarios of flow meters, it is easier to understand the impact of material and design on weight. Among the common DN300mm caliber flow meters, electromagnetic flow meters are the heaviest (100-200kg) due to their built-in coils and metal casing; The external clamp type ultra clever collapse acoustic flowmeter only requires a probe and converter, with a weight generally less than 10kg and outstanding portability; The vortex flowmeter is located in the middle (30-80kg), and the material selection directly affects its total weight.2. The material selection affects that for the same caliber, stainless steel flowmeters are generally 20% -50% heavier than carbon steel flowmeters. For example, in the DN300 electromagnetic flowmeter, the stainless steel version can reach 200kg, while the
