Ultrasonic Flow meter china
Ultrasonic Flow meter model TDS-100 from china manufacture was established in 1996. Our firm is a high technology company which specializes in design, manufacture and development. TDS-100 series of ultrasonic flow meters / calorie meters / water meters are widely used in the oil, chemical, metallurgy, water conservancy, heating, and boiler industries. TDS-100 Ultrasonic flow meter are exported to the United States, Europe, Australia, Japan, Korea and Southeast Asia. We have achieved a sales volume of over fifteen thousand sets per year.
The new instruments are invented based on the 7 version, 11 version ultrasonic flow meters and the 9 version ultrasonic water meter, it integrates many years’professional technology of manufacturing and experiences, adopts TI’ low consumption single device MSP430FG4618 invented up to date the high function, low price, good reliability, power function, new series products. enhanced greatly in the aspects of measurement accuracy, measurement stability, communication protocol, easy to use etc. than previous versions. at the same time, it achieved no adjustment of ic parameter during production, easy and reliable production line, good conformity of the products, guarantee each instrument reach the best function before leaving factory.
It continues to use the friendly user menu of the 7 version ultrasonic flow meter for software operating, only few menu function is changed or added,make old customers feel free to grasp in order to meet the users custom, we invented another 4 keys parallel port keyboard on the basis of 16 keys applied for economical style, in-line style ultrasonic flow meter, two key boards can be exchanged to use.
TDS-100 has 3 types of transducer installation method :
Clamp On type transducer flow meters Installation
Before installation, choose density pipe to install transducers, and clean the installation area, clear away rust, paint, anti-rust layer, it is the best to use angle grinder to polish, use cleaning cloth with alcohol or acetone to clear oil and dust, coat enough couplant around the center of installation area, attach the transducers on the pipe and fix it without air bubbles or sand between transducers and pipe wall. Clamp on type transducer has 3 sizes Small , Medium size and large size.
Insertion type transducer flow meters installation
Transducers can be installed directly on pipes of carbon steel or stainless steel by welding; while for those pipes of materials like cast iron, glass fiber reinforced plastic, PVC and cement which cannot be welded directly, special straps should be used for installation. For those users who are in similar situation, please inform us of the precise outside diameter of the pipe to be installed to prevent leakage
In-line type transducer flow meter installation
In-line type transducer of new TDS-100 ultrasonic flow meters is characterized by easy installation and high-accuracy measurement. When ordering, customers need to provide the actual parameters of the pipe. The parameters of the transducer have been put into the flow meter before leaving factory and there is no need to input them when installing.
Type of TDS-100 Ultrasonic Flow Meter :
Hand Held Ultrasonic flow Meters Flowmasonic WUF-100J Ultrasonic Flow Meters Portable Flow Meters
The WUF-100J 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. The WUF-100J transit timeultrasonic 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 ultrasonic hand held 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.
WUF series Handheld Ultrasonic Flow Meters are based on clamp-on transit-timeflow measurement principle. It measures the flow rate of liquid in a pipe from outside of the pipe by using a pair of ultrasonic transducers. In general, the liquid should be full in the pipe, and should contain very little particles or bubbles. It is applicable for water (hot water, chill water, city water, sea water, etc.); sewage; oil (crude oil, lubricating oil, diesel oil, fuel oil, etc.); chemicals (alcohol, acids, etc.); waste; beverage and liquid food, solvents and other liquids. WUF-100J handheld ultrasonic flow meter is a battery-powered ultrasonic flow meter with the capability of a full-size flow meter. It is carefully designed for portability and ease of use.
WUF-100J portable type ultrasonic flow meter adopts built-in chargeable nickel-hydrogen batteries, which can work for about 20 hour after fully charged. It adopts intelligence charging method. The operator should insert one end of the configured power wire into the AC 220V port of the right side of the machine, and inserts the other end into the electrical outlet (AC 220V), and then the charging operation could be finished. After connecting the wires, the red light on the keyboard of the machine will glitter , which means it’ s charging. When it is fully charged, the red light will turn to green. Then the operator can pull out the wires and put away for nest use.
TDS-100Y Compact Ultrasonic Flow Meters
In Line Ultrasonic FLow Meters Compact Ultrasonic FLow Meter Integral Ultrasonic Flow Meter TDS-100Y ultrasonic flow meter /heat meter:, it make the main board of TDS12 or TDS18 connect to a 20 lines 4 keys parallel port keyboard monitor, then encapsulate them in a sealed enclosure, realize on-line display and operation on spot. It solved the problem that owing to the reason of people that make the measured pipe parameters inaccuracy, caused errors that lowered the measurement accuracy during the period of installing the clamp-on type and insertion type transducers .it has the advantages of high accuracy, wide measurement range, no pressure lost, easy installation, no need to set parameter, etc. It is the future for the flow meter and heat
