dn500 Vortex Flowmeter

Vortex flowmeter is mature and reliable sensing piezoelectric sensor technology, its vortex flowmeter According to the conditions characteristic of demand can be velocity, flow (or temperature conditions, pressure testing to optimize one), fully reflects the vortex flowmeter today's high-tech mechatronics products and its price. The vortex flowmeter instrumentation systems using Microchip's MCU data processing technology combined with modern microelectronic technology research and development of a highly reliable, high accuracy industrial flow measurement and control instruments. Vortex flowmeters are widely used measurement in closed conduits steam, gas and liquid medium flow. Vortex flowmeter vortex flowmeter to measure the volume of gas flow meters, steam or liquid volume flow, standard condition volume flow or mass flow according to Carmen (Karman) vortex principle. Set triangular columnar vortex flowmeter vortex shedder in the fluid from the vortex of both sides alternately produce a regular vortex, this vortex is called Karman vortex, as shown below, the non-occurrence of vortex column downstream vortex body arranged symmetrically. To vortex flowmeter easy to use, battery-powered local display type vortex flowmeter micro-power high-tech, the vortex flowmeter powered by lithium batteries can run for more than a year without interruption, saving cable and display instrument procurement and installation costs , may display the instantaneous flow, cumulative flow. Temperature compensation of a vortex flowmeter with integrated temperature sensor can directly measure the temperature of saturated steam and pressure is calculated to show the mass flow of saturated steam. Temperature and pressure compensation integrated with temperature and pressure sensors, vortex flow meter for gas flow measurement can directly measure the temperature and pressure of the gas medium to display standard conditions of gas volume flow. ◆ Measuring media: gas, liquid, vapor ◆ Specifications Falanca mounted caliber caliber select 25,32,50,80,100 ◆ flanged caliber Select 100,150,200 ◆ normal flow measurement range velocity measurement range of Reynolds numbers 1.5 × 104 ~ 4? ? × 106; gas 5 ~ 50m / s; liquid 0.5 ~ 7m / s normal flow range measuring liquid, gas flow measurement range shown in Table 2; see Table 3 ◆ vapor flow range Accuracy 1.0 1.5 ◆ measured medium temperature: room temperature -25 ℃ ~ 100 ℃ ◆ high temperature -25 ℃ ~ 150 ℃ -25 ℃ ~ 250 ℃ ◆ output signal pulse voltage output signal high 8 ~ 10V 0.7 ~ 1.3V ◆ low pulse duty of about 50% transmission distance of 100m ◆ pulse current remote signal 4 ~ 20 mA, transmission distance of 1000m ◆ meter Ambient temperature: -25 ℃ ~ + 55 ℃ Humidity: 5 ~ 90% RH50 ℃ ◆ Material Stainless steel, aluminum ◆ Power DC24V or Product Selection ◆ measuring medium lithium battery 3.6V ◆ Explosion levels intrinsically safe iaIIbT3-T6 Protection class IP65 vortex flowmeter: gas, liquid, vapor ◆ Specifications Falanca mounted caliber caliber select 25,32,50,80,100 ◆ flanged caliber Select 100,150,200 ◆ normal flow measurement range velocity measurement range of Reynolds numbers 1.5 × 104 ~ 4 × 106;? gas 5 ~ 50m / s; liquid 0.5 ~ 7m / s normal range of liquid flow measurement, gas flow measurement range Table 2; see Table 3 ◆ vapor flow range Accuracy 1.0 1.5 ◆ measured medium temperature:? normal temperature -25 ℃ ~ 100 ℃ ◆ high temperature -25 ℃ ~ 150 ℃ -25 ℃ ~ 250 ℃ ◆ output signal pulse voltage Output signal high 8 ~ 10V 0.7 ~ 1.3V ◆ low pulse duty about 50%, the transmission distance of 100m ◆ pulse current remote signal 4 ~ 20 mA, transmission distance of 1000m ◆ meter Ambient temperature: - 25 ℃ ~ + 55 ℃ Humidity: 5 ~ 90% RH50 ℃ ◆ Stainless steel, aluminum product selection ◆ Power DC24V or lithium battery 3.6V ◆ Explosion levels intrinsically safe iaIIbT3-T6 Protection class IP65 Vortex Flowmeter Code through Runoff range m / h ST-LU-25 DN25 1 ~ 10 (liquid) 25 to 60 (gas) steam flow Check the manual, DN300 above recommended insertion vortex flowmeter ST-LU-32 DN32 1.5 ~ 18 ( liquid) 15 to 150 (gas) ST-LU-40 DN40 2.2 ~ 27 (liquid) 22.6 150 (gases) ST-LU-50 DN50 4 ~ 55 (liquid) from 35 to 350 (gas) ST-LU-80 DN80 9 ~ 135 (liquid) 90 - 900 (gas) ST-LU-100 DN100 14 ~ 200 (liquid) 140 to 1400 (gas) ST-LU-150 DN150 32 ~ 480 (liquid) 300 to 3000 (gas) ST- LU-200 DN200 56 ~ 800 (liquid) 550 - 5500 (gas) code Function 1 N no temperature and pressure compensation Y have temperature and pressure compensation Code Output Model F1 4-20mA output (two-wire) F2 4-20mA output (three-wire) F3 RS485 communication interface, code-named test medium gas J3 J2 J1 liquid vapor Symbol Connection L1 L2 Fa Lanka mounted flanged code Function 2 E1 1.0 级 E2 1.5 级 normal T1 T2 T3 high temperature steam P1 1.6MPa P2 2.5MPa P3 4.0MPa D1 D2 DC24V internal 3.6V power supply B1 B2 stainless steel
