1. Classification of Ultrasonic Flowmeters
Ultrasonic flowmeters can be classified according to the following principles.
(1) Measurement principle Time difference ultrasonic flowmeter; Frequency difference method ultrasonic flowmeter; Phase difference ultrasonic flowmeter; Doppler ultrasonic flowmeter; Non full pipe and channel ultrasonic flow meters combining liquid level measurement and average flow velocity measurement.
(2) Usage: Portable ultrasonic flowmeter, features: portable use, built-in rechargeable lithium battery, suitable for mobile measurement, equipped with magnetic sensor.
. Fixed (standard pipe section) ultrasonic flowmeter.(3) The installation method of the transducer is a standard pipe section ultrasonic flowmeter, which requires cutting the pipeline for installation, but can be maintained without stopping production in the future.
. You can choose between mono or tri channel sensors. External clamp type ultrasonic flowmeter, characterized by the ability to complete fixed and mobile measurements. The use of specialized coupling agents (room temperature cured silicone rubber or high-temperature long-chain polymer grease) is recommended for installation without damaging the pipeline. On site perforated insertion ultrasonic flowmeter.(4) Whether the transducer is in contact with the fluid or not. Ultrasonic pure flow meter with insertion type, features: can be installed and maintained without stopping production.
. Non contact (external clamp) ultrasonic flowmeter.(5) Properties of the measured fluid: liquid ultrasonic flowmeter; Gas ultrasonic flowmeter.
(6) Number of transducer channels Single channel ultrasonic flowmeter; Two channel ult
2. Installation and use instructions for portable Doppler ultrasonic flowmeter
The installation and use of portable Doppler ultrasonic flowmeter need to be combined with equipment principles, technical characteristics, and operating specifications. The specific process is as follows:
1. Equipment principles and core functions. Portable Doppler ultrasonic flowmeter works based on Doppler effect and velocity area method: Doppler effect: by measuring the frequency shift of scattered sound waves by moving particles in the fluid, the fluid flow velocity is calculated.
. Velocity area method: combining flow velocity with cross-sectional area (water level) to calculate flow rate, suitable for full and non full pipe environments, and can freely set the water level cross-sectional relationship coefficient. Technical parameters: Flow rate range: 0.02-5m/s, resolution 1mm/s. Response time: Real time refresh of measurement results. Storage space: 16MB, capable of storing over 100000 pieces of data. Battery life: Equipped with a built-in lithium battery, it can work continuously for over 12 hours. Display: The LCD screen displays real-time flow rate, flow rate, water level, and water temperature.2. Installation steps and precautions 1 Probe installation fixed probe: Fix the probe to the bracket, hold the stainless steel measuring rod, and insert the probe into the water body. Direction and position: The probe is facing the direction of water flow, ensuring that the water flow in the measurement area is uniform and stable. There are no obstacles (such as stones, sediments, garbage, etc.) in front of the pro
