BST Ultrasonic Flowmeter

Current location:Home page -> Product -> Liquid Flowmeter

■Product Introduction
BST ultrasonic flowmeter is the perfect combination of ultrasonic technology and electronic technology. To accurately determine the ultrasonic sound waves in the fluid propagation time or frequency changes to measure the flow of fluid, is an energy-saving instrument. In fact, the use of intelligent, long-term stability and the realization of computer networking and other aspects of the traditional flowmeter has an unparalleled advantages.

Ultrasonic flowmeter and electromagnetic flowmeter, because the instrument flow channel does not set any obstructions, are unimpeded flowmeter, is suitable for solving the problem of flow measurement problems A class of flow meters, especially in large diameter flow measurement has more prominent advantages The But also in recent years to develop more rapid flow meter one.

Exquisite brand ultrasonic flowmeter, the use of advanced technology design and manufacturing for industrial environments without continuous measurement of large concentrations of suspended particles or gas without the vast majority of clean uniform liquid flow can be applied to a variety of liquid long-term online measurement, extensive For water, heating, water, metallurgy, chemicals, machinery, energy and other industries. Exquisite ultrasonic flowmeter according to the host type can be divided into: portable, handheld, fixed one, wall-mounted, plate mounted, explosion-proof.

■ Product Features
One.  To achieve the installation and measurement of the tube, the tube fluid does not produce pressure loss, saving energy without leakage, no pollution and no         corrosion.
Two.  Installation and maintenance convenient, does not affect the production.
Three.  The use of single-chip, can easily enter the diameter, pipe, fluid and other related parameters, strong adaptability.
Four.  With power-down detection, data protection, and then power to resume operation.
Five.  Anti-interference ability, can work in harsh environments.
Six.  Performance and price ratio is better than similar imported instruments, and the price does not increase with the increase in diameter.

■ Installation method
Ultrasonic flowmeter consists of two parts: the probe and the measuring host. The probe is installed in the outer wall of the pipe. The installation method is Z-type, V-type and X-type according to the size of the pipe. Probe and measurement between the host with the probe cable connection, probe cable length see the technical parameters table (see the installation instructions for specific installation). Straight pipe requirements: measuring probe should meet 10D, after receiving the probe should meet the 5D (D for the pipe diameter)
