LZ metal tube chemical rotameter , variable area gas flow meter in china

 LZ Metal Tube Chemical Rotameter , variable area  gas flow meter in china
Introduction LZ steel rotor pipeline flow meter is reliable equipment which has simple structure, wild using range, high accuracy and low cost. The flow meter is available in local visual reading, data transmissible, anti-corrosion and explosive-proof types. It is wildly used for liquid & gas measuring and control in national security, chemical, petroleum, pharmaceutical, and light industrial. metal tube chemical rotameter
  The sensors of the equipment are available in stainless steel (1Cr18Ni9Ti), MoTi II (0Cr18Ni12Mo2Ti, 1Cr18Ni12Mo2Ti) and PTFE. Other special materials are available for order, in order to measure corrosive fluid, i.e. Chlorine, Salt, Hydrochloric Acid, Nitric Acid and Sulfuric Acid.   Data output in standard signal, it can be fitted with DDZ-III electrical unit for computer control, implement comprehensive control.   Measuring theory The float moves when fluid flow through cone pipeline from bottom to top. It stay still when buoyancy A, damping force W equal the weight of float G. The position of float stands for current flowing rate. It moves needle which fitted with two magnets, which shows current flowing rate.   Specification 1.Measuring range: Water: 2.5 ~ 63,000L/h; Air: 0.07 ~ 2,000 m3/h (0.1013MPa, 20°C) 2.Measuring ratio: 10:1 (other special ratio equipment can be made by order) 3.Accuracy level: 1.5; 2.5 4.Maximum working pressure: 1.6MPa, 2.5MPa, 4.0MPa, 6.4MPa (Please quote individually for pressure greater than 6.4MPa) 5.Application temperature: -80 ~ +300°C (For anti-corrosion PTFE: 0 ~ +80°C) 6.Working environment temperature: -20 ~ +50°C 7.Application viscosity: φ15 <5mpa·s; φ25 ~φ100 <250mpa·s 8.Connection: flange: Flange standard: 1.6, 2.5, 4.0, 6.4MPa, according to GB/T17241.6-68 (Other special order available, please quote individually) 9.Product type: LZZ: standard; LZD: data transmissible.   Flow range
