Ultrasonic liquid Flow Meter
Introduction
ZR-3000P (Version 13.0) ultrasonic flow meter that has been manufactured with patent technologies and is equipped with more functions and advanced performance than our previous versions.
The Version 13.0 series ultrasonic flow meter has been upgraded based on the Version 10.0 series ultrasonic flow meter, which is still the main product line of the company. The new Version 13.0 retains most of the excellent features and functions of the previous versions: the pulse measurement technology, the ultrasonic igniting and the small signal receiving circuits etc. The main improvements are made on the isolation power supply and on the isolation RS485 serial port.
ZR-3000P flow meter incorporates the latest ICs manufactured from the famous semiconductor manufacturers like Philips, Maxim, TI, Winbond, and Xilinx. The hardware features the ease of operation, high accuracy and outstanding reliability, while the software provides a very user friendly interface and much more functions. It employs a patent balanced lower voltage multi-pulse igniting circuit which increases the anti-interference ability magnificently so that the flow meter will work properly even in demanding industrial environments such as those with power frequency transverter working nearby.
Features
1.High accuracy: Linearity: 0.5%, repeatability:0.2%, accuracy up to ±1%.
2.Non-contacting measuring: The ultrasonic flow meter will be adsorbed on the outside of pipe, and then finish the measuring. Non-intrusive, clamp-on transducer, no pressure drop, no pipe disturbance.
3.Wide measuring range: Several types transducer for selection, pipe size from DN15mm to DN6000mm
4. Chinese & English menu: Chinese & English display, easy to operate.
5.Large capacity battery: Built-in rechargeable Ni-MH rechargeable battery, provide over 20 hours of continuous operation.
6.Built-in printer: Built-in mini thermal printer with instant and timing print function, also you can print more than 20 kinds of measuring results if you set in advance.
7. Built-in data logger: Uplink over 20 measuring data to computer or Internet.
Principle of Measurement
ZR-
3000P ultrasonic flow meter is designed to measure the fluid velocity of liquid within a closed conduit. The transducers are a non-contacting, clamp-on type, which will provide benefits of non-fouling operation and easy installation.
ZR-3000P transit time flow meter utilizes two transducers that function as both ultrasonic transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a specific distance from each other. The transducers can be mounted in V-method where the sound transverses the pipe twice, or W-method where the sound transverses the pipe four times, or in Z-method where the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once. This selection of the mounting method depends on pipe and liquid characteristics. The flow meter operates by alternately transmitting and receiving a frequency modulated burst of sound energy between the two transducers and measuring the transit time that it takes for sound to travel between the two transducers. The difference in the transit time measured is directly and exactly related to the velocity of the liquid in the pipe, as shown in the following figure.
Where
θ is the include angle to the flow direction
M is the travel times of the ultrasonic beam
D is the pipe diameter
Tup is the time for the beam from upstream transducer to the downstream one
Tdown is the time for the beam from downstream transducer to the upstream one
ΔT=Tup –Tdown
Applications
ZR-3000P flow meter can be virtually applied to a wide range of measurements. The measured pipe ranges 15-6000mm. Because the instrument and transducers are non-contacting and have no moving parts; the flow meter can not be affected by system pressure, fouling or wear. Standard transducers are rated to 110 oC.
