Product description

Clamp-on, plug-in, pipe-stage ultrasonic flow meter are "speed difference method" as the principle of measurement
The amount of liquid in the tube flow meter. It uses an advanced multi-pulse technology, digital signal processing technology
Operation and error correction technology, the flow meter can adapt to the industrial field environments, measuring more convenient, economical,
accurate. Products reach the international advanced level, can be widely used in petroleum, chemical, metallurgy, electric power,
Water supply and drainage, and other fields.
Measuring principle
Ultrasonic flowmeter uses the time difference measuring principle: a probe transmission signal passes through the wall, medium,
After the other side of the wall, another probe is received, while the second probe signal is also launching the first
A probe is received, the media due to the impact velocity, the two time difference Δt, according to projections
It can be drawn in terms of the relationship between flow velocity V, and the time difference Δt between V = (C2 / 2L) × Δt, and then you can get
Flow rate Q
1 operating principle of transit-time
 
Product Features
Ultrasonic flowmeter is a non-contact instrument, it can measure the flow of large diameter media also
It can be used to measure the medium's reach and observation. Its high measurement accuracy is hardly affected
The interference of various parameters measured media, in particular, can not solve the other instruments of strong corrosive, non-conductive
Flow, radioactive and explosive media measurement problems. Clamp-on ultrasonic flow or pipe-stage
Instrumentation is "speed difference method" as the principle of measuring the inner tube of liquid flow meter. It uses an advanced
Multi-pulse technology, digital signal processing and error correction technology, the flow meter can adapt to current industry
Field of environment, measurement more convenient, economical and accurate. Products reach the international advanced level, it can be widely
Used in petroleum, chemical, metallurgy, electric power, water supply and drainage, and other fields.
