1. Main technical parameters of metal rotor flowmeter
The main technical parameters of metal rotor flowmeter are summarized as follows
1. Basic specifications: Measurement range: When water is at 20 ℃, the flow range is 2.5-150000L/h; Under the same conditions, the flow rate range of air is 0.07-4000Nm3/h. Range ratio: 10:1, ensuring measurement accuracy. Accuracy: There are two accuracy levels to choose from: 1.5 and 2.5. Work pressure: Supports a maximum of 6.4MPa and is suitable for various application scenarios. Working temperature: -40 ℃ to 350 ℃ (fluoroplastic lining models are suitable for -10 ℃ to 80 ℃). Environmental temperature: The operating range is from -20 ℃ to 80 ℃. Medium viscosity: The viscosity in DN15 pipelines should be less than 5mPa. S, while the viscosity in DN25 to DN150 pipelines is limited to 250mPa. S. Tube material: Optional materials include 1Cr18Ni9Ti, 316L, and lined with PTEF. Process balance chain connection: flange connection is usually used, but other connection methods can also be provided according to user needs. Steam coupling: flange connection, DN15/PN1.6 specification, also supports user customization
2. Remote transmission device options: GD 5W1-1 angular displacement transmitter: basic error 1.5% F.S, output signal 4-20mA, power supply voltage 24VDC, explosion-proof grade ExibIICT4. GD E-HD transmitter: has extremely low power and load effects, current loss is related to the measured value, working voltage is 12.8-30VDC, explosion-proof return signal level ExibIICT6. In addition, the LZ series metal rotor flowmeter offers a selection of different diameters and flow ranges, including conventional and anti-corrosion types, and pressure loss also varies accor
2. What parameters are required for the selection of a rotor flowmeter?
1. For the selection of remote output metal tube float rotor flowmeter, it is necessary to choose a rotor flowmeter that is suitable for the explosion-proof requirements of the application site; During installation, attention should also be paid to the fastening of the instrument casing and the sealing of the wiring ports after power on, to meet the requirements of explosion prevention, protection, and corrosion prevention. 2. For places where the temperature of the measured medium is too high (>120 ℃) or too low, insulation or heat insulation measures should be taken for the sensor part of the rotor flowmeter. To ensure the normal working environment temperature of the signal converter indicator, a high temperature indicator should be selected. 3. For some measured media that require insulation or cooling, a jacket type rotor flowmeter should be selected. The heat tracing or cooling bucket of the standard metal tube float rotor flowmeter adopts DIN2501 DN15 PN1.6 flange connection for this grip interface. If other flanges or threaded connections are required, please specify
4. For the unstable pressure of the inlet medium of the rotor flowmeter, especially for gas measurement, damping structure should be selected to ensure accuracy and service life.
5. For the medium with high pressure requirements, when exceeding the standard pressure level, please choose high-pressure structure when selecting, and use HG20595-97 RF neck welded steel pipe flange for high-pressure type. If other standards are used, please indicate
