Introductiong of RBTG Series Ultrasonic In-line Flow Sensors

 RBTG Series Ultrasonic In-line Flow Sensors

 

About R&B: R&B is a high-tech company dedicated to the research, development, manufacturing, and sales of ultrasonic sensor products. Our team has profound experience in technical innovation, product development and international marketing of acoustic sensors and related circuit systems. We focus on the application of ultrasonic sensors in fluid measurement and control. One of our core competences lies in the solutions for small tubing diameters and low flow rates. Our sensors are accurate, reliable and intelligent, and are widely used in medical equipment, biopharmaceuticals, semiconductor manufacturing, scientific research, industrial monitoring, and food and beverage production.

R&B's TG series ultrasonic in-line flow sensors are compact in size, and can measure flow and output results without external circuitry.  The sensors can be integrated into flow lines via the fluid connectors to perform measurement with excellent accuracy, sensitivity, and reliability. With straight-through flow/measuring channels incorporated, the sensors do not contain any removable part or dead area. They are easy to clean and have very low pressure loss. Compared to a clamp-on sensor, the calibration of an in-line flow sensor is not affected by tubing materials and sizes. Once plugged in, the in-line flow sensor can perform measurement immediately. The in-line flow sensors can be used in semiconductor manufacturing, food and beverage production, scientific tests, filling and spraying processes, etc. 

Features:

l High precision and high stability

l Bi-directional measurement, can calculate fluid volume and detect air bubble

l Circuit embedded in the sensor and no external circuit required

l No blockage, no dead area, low fluid pressure loss

l Provide standard output methods to seamlessly integrate with customer systems

Applications:

l Medical devices tests, such as the validations of hemodialysis machine, organ transplantation system, heart-lung machine, and blood pump

l Biopharmaceutical processes and equipment, such as fermenters, cell culture equipment, vaccine production, tangential flow filtration systems, and liquid chromatography

l Fluid monitoring during semiconductor manufacturing, such as high purity water 

l Food & beverage processing, such as milk, juice, and beer production

l Filling equipment, spraying equipment, cooling system, and lubrication system

l Scientific experiment system

l Water treatment and wastewater treatment system
