| Metal tube rotameter is a kind of variable area flow meter commonly used in industrial automation process control. The utility model has the advantages of small volume, small pressure loss, convenient installation and maintenance, etc. It can be used to measure liquid, gas and steam, especially suitable for medium flow measurement with small flow rate and low flow rate. It is widely used in petroleum, chemical industry, steel, electric power, metallurgy, light industry, food, pharmaceutical, water treatment and other industries. |

Metal tube rotameter -- first choice for measuring medium flow with small flow rate and low flow rate performance Nominal diameter: dn15-dn200 precision: ± 2.5% Bureau Medium temperature: normal temperature - 40 ° C to + 100 ° C, PTFE: 0 ° C to + 120 ° C, high temperature + 100 ° C to + 450 ° C Pressure rating: Standard Type: dni5 ~ dn50pn4.0mpa (special type 25MPa) Standard type: DN80 ~ DN100 pni.6mpa (special type 16MPa) Pressure grade of jacket: 1.6Mpa, various power supply modes shall be negotiated with the factory before selection and ordering of special type: Standard Type: 24VDC (10.8vdc ~ 36VDC) AC type: 220VAC (85 ~ 265vac) Battery type: Powered by lithium battery, it can be used continuously for more than three years with double indication system, improving the reliability of the instrument The magnetic coupling and magnetic signal are separated, so the flow caliber is complete without the influence of medium temperature, ferromagnetic particles and caliber size. It has great advantages in small flow measurement, good explosion-proof performance, and can be used in flammable and explosive dangerous occasions The whole series of installation methods meet different customer requirements: lower in and upper out, lower in and upper out, lower in and upper out, right in and left out, left in and right out, upper in and lower out, flange connection, threaded connection, sanitary clamp connection, etc High integrated circuit brings high reliability Multiple output modes: local display, 4 ~ 20mA, switch value alarm, Hart, MODBUS Double line LCD digital display PTFE inner village is suitable for measuring anti-corrosion medium Low requirements for straight pipe section With data recovery, data backup and power failure protection functions |
