Introduction: Turbine flowmeter is a new generation of turbine flowmeter with the characteristics of simple structure, light weight, high precision, good repeatability, sensitive response, convenient installation and maintenance, and is widely used in measuring closed flowmeters. In the pipeline, with stainless steel 1Cr18Ni9Ti, 2Cr13 and corundum Al203, cemented carbide does not corrode, and has no impurities such as fiber particles, and the kinematic viscosity at working temperature is less than 5x10-6m²/s. For liquids with kinematic viscosity greater than 5x10-6m²/s Liquid, can flow The meter is used after real-liquid calibration. If it is matched with a display instrument with special functions, it can also carry out quantitative control, excess alarm, etc. It is an ideal instrument for flow measurement and energy saving. Features: 1. High precision, generally up to +1%R, +0.5%R, high precision type up to +0.2%R; 2. Good repeatability, short-term repeatability can reach 0.05%~0.2%, it is precisely because of good repeatability, such as frequent calibration or online calibration, high accuracy can be obtained. The flow meter is the preferred choice in settlement; 3. Output pulse frequency signal, suitable for total measurement and connection with computer, no zero drift, strong anti-interference ability; 4. The range is 1:20 for medium and large calibers, and 1:10 for small calibers; 5. Compact and lightweight structure, easy installation and maintenance, and large flow capacity; 6. It is suitable for high pressure measurement, and there is no need to open holes on the meter body, and it is easy to make a high pressure meter; 7. There are many types of special sensors, which can be designed into various special sensors according to the special needs of users, such as low temperature type, bidirectional type, downhole type, special type for sand mixing, etc.; 8. It can be made into a plug-in type, suitable for large-diameter measurement, with small pressure loss, low price, continuous flow and extraction, and convenient installation and maintenance. Technical parameter: Executive standard: Turbine flow sensor (JB/T9246-2016) Instrument diameter (mm) and connection method: 4, 6, 10, 15, 20, 25, 32, 40, 50, 65, 80 are connected by thread Accuracy class: ±1%R, ±0.5%R, ±0.2%R (requires special order) Turndown ratio: 1:10; 1:15; 1:20 Sensor material: 304 stainless steel, 316 (L) stainless steel, etc. Conditions of use: Medium temperature: -20℃～+120℃ Ambient temperature: -20℃～+60℃ Relative humidity: 5%～90% Atmospheric pressure: 86Kpa～106Kpa Signal output function: pulse signal, 4～20mA signal Communication output function: RS485 communication, HART protocol, etc. Working power supply: External power supply: +24VDC±15%, ripple ≤±5%, suitable for 4-20mA output, pulse output, RS485, etc. Internal power supply: 1 set of 3.0V10AH lithium battery, the battery voltage can work normally when the battery voltage is 2.0V ~ 3.0V. Signal line interface: Internal thread M20*1.5 (NPT thread needs to be customized) Explosion-proof grade: ExiaIICT6 Gb Protection class: IP65 or higher (can be customized)
