Turbine flowmeter Product name: turbine flowmeter Product code: 164912-752 Update time: 2015.08.25 Views: 346 Processing custom origin: in kaifeng Type: type flow meter LWG series Type: impeller type flowmeter Measuring range: 0.4-20000 (m3 / h) Level of accuracy: + / - 1.5% Nominal size: 10-500 (mm) Working pressure: 2.5, 6.3, 16 Working temperature: - 20 ~ 55 ℃ Summary: Turbine flowmeter can be divided according to function name gas flow meter,flue gas meter,steam flow meter,gas flow meter,compressed air flow meter,liquid flow meter. LWG type turbine flow sensor and receiving electrical signals of the display instrument of Turbine flowmeter, which is used to measure low and medium viscosity closed pipes Degree of fluid (liquid or gas), the total volume flow and in petroleum, chemical industry, metallurgy, aviation and scientific research departments for a wide range of applications. Sensor is composed of turbine sensor components and amplifier, the structure of the two together for one-piece: to measure the structure of the positive and negative flow For two-way type; With inserted rod can be installed in the large diameter pipe flow body flow structure for a plug-in. Based on the principle of moment balance sensor work. When the fluid flows through the sensor, promote the impeller rotation, when the flow rate must be dynamic torque Maintain and drag torque balance, the impeller speed. Evenly distributed on the permeability of the impeller blade with the impeller rotation, to periodically change detection The reluctance of the magnetic field sensor (coil), electrical pulse signal detector, after the amplifier amplification output. The output electric pulse frequency and impeller speed Is proportional to the impeller speed is proportional to the flow in, so the output electric pulse frequency is proportional to the flow sensor flow, 4-20 ma signal is converted is proportional to the flow. Features: 1) impurity resistance is strong, tangential impeller rotating at can release floating debris in the fluid at any time, when the winding on tangential impeller blades. 2) resistance to electromagnetic interference and strong vibration resistance. 3) the structure and principle of the sensor and display instrument is very simple, user especially easy to master its use and maintenance technology. 4) after replacement of impeller and bearing, meter coefficient is constant. 5) wide flow range, lower limit velocity is low. 6) complete sets of flow meter for the measurement of the fluid volume error is small. 7) almost no pressure loss, save power consumption. 8) sensor can be installed in open air, the sensor can be submerged in the water use for a long time. 9) have a globe valve sensor, install and remove all don't need to stop. 10) horizontal, vertical, inclined pipe can be used. 11) complete sets of flowmeter the purchase, installation, and low cost. The main parameters: Pulse output, linear characteristic; High precision, responsive; Measurement of wide flow rate range Signal output, pulse output (+ 12 + 24 VDC power supply, three wire system) pulse output (+ 24 VDC power supply, two wire) 4-20 madc simulation flow signal output Explosion-proof categories: d II BT3, ib IICT3 Simple structure, convenient installation, use and maintenance; And can supply complete set of filters, gets the whole straight (flow); Can provide installation with matching pair of flange pair (2) only Nominal diameter: pipeline: DN4 ~ 12 Plug-in: DN100 ~ DN2000 Precision level: pipeline: plus or minus 0.5, plus or minus 1.0 on the Richter scale, plug-in: 1.5 mm, 2.5 mm high precision can reach 0.2 Ambient temperature: - 20 ℃ to 50 ℃ Medium temperature: liquid measurement: - 20 ℃ ~ 120 ℃ Measuring gas: - 20 ℃ ~ 80 ℃ The atmospheric pressure: 86 kpa to 106 kpa Nominal pressure: 1.6 Mpa, 2.5 Mpa, 6.4 Mpa, 25 Mpa Connection mode: threaded connection, flange clamp outfit, flange connection, plug, etc
