Insertion ultrasonic flowmeter

Description

It is a meter consisting of 2 parts, i. e. the conversion unit and insertion-type transducer working on the “velocity-difference” principle for flowrate measurement. Because of the use of advanced multi-pulse, signal processing and error correction technologies, the meter is highly adaptable to industrial working conditions. The meter can be mounted on site with the aid of Huizhong’s special drilling apparatus – a tool capable of opening holes on pipe under pressure of pipe flow, without the need to shut down the pipe flow. Therefore, the mounting cost can be greatly reduced. Various output functions are available: RS**5, ***0mA, ***0mA, cumulative pulse and GSM radio transmission. Fluid measured: Water, sewage and other homogeneous fluids in full pipe flow. Accuracy, %: ±1.0. Flow velocity adaptable, m/s:±0.**-±*2. Pipe size adaptable, mm: DN**-DN***0. Transducer material: 1Cr*8Ni9Ti (Stainless steel) Maximum pressure-bearing capacity of transducer Max. pressure at local places in pipe: <2MPa Immersion depth of transducer<3 m Working Environment:Conversion unit Temperature: **0℃~**5℃ Humidity: *5% (RH) (For use under otherwise specific conditions, please specify on ordering). Transducer:Normal temperature type: 4~*0℃ High temperature type: 4~**0℃. Cable: **0℃ - **0℃.
