Cheap ultrasonic flowmeter
Description of ultrasonic flowmeter :
Ultrasonic flowmeter can be divided into outside the pipe clamp mounted and plug-in installed two kinds, connection mode can be DC24V power supply, can also be DC220V power is optional. Explosion-proof grade Exd Ⅱ BT4, especially for the working condition of the chemical industry with explosion-proof required measuring flow.
Features of cheap ultrasonic flowmeter :
1. Explosion-proof ultrasonic flowmeter with large planning integrated circuits CPLD, table process, accuracy is higher.
2. High reliability, high performance, good applicability, full display in Chinese.
3. Day, month and year flow accumulation function, can record run 64 days before the operation, the first 64 months, the first five years of accumulated flow operation.
4. Effectively overcome the wall of the ultrasonic signal attenuation and rough surface of the pipe to scattering of ultrasonic signal from surface reduce the energy consumption of ultrasonic signal.
5. Explosion-proof type ultrasonic flowmeter to overcome the signal to a small amount of sediment, suspended particles and bubbles, the effect of improved flow measurement accuracy, especially suitable for pipe flow measurement.
6. Using a special opening tools make the sensor in the zone without water supply installation, unique belt roller disassembly, installation method, does not affect the normal production, at any time to complete the online replacement and maintenance.
Detailed parameters of ultrasonic flowmeter :
1. Measuring liquid: water, sea water, a single fluid, such as alkali, and the turbidity is less than 10000 PPM, particle size less than 1 mm
2.PVC pipe material: steel, cast iron, pipe ultrasonic can penetrate the full package, such as dense texture, and no serious corrosion and scaling allows thin layer compact lining
