What is an Ultrasonic Flowmeter? Flow Meter Types and Applications.

 


An ultrasonic flowmeter is a type of flow meter that uses ultrasonic waves to measure the flow rate of a fluid. This technology works by sending ultrasonic pulses through the fluid and measuring the time it takes for the pulses to travel between two points in the flow stream. By analysing the difference in time between upstream and downstream pulses, the flow rate of the fluid can be calculated. The solution specialist for innovative ultrasonic measurement technologies divided into three independent business units: Non-Invasive Fluid Monitoring and Ultrasonic Transducers.

There are two main types of ultrasonic flow meter types：

1. Transit Time (Time of Flight) and Doppler, are both available in a clamp-on meter style with transducers which are used to detect and then measure flow rates from the outside of the pipework, without any interruption to flow or process. 

2. Doppler flow meters work by measuring the frequency shift of reflected ultrasonic waves off of particles or bubbles in the fluid, while transit-time flow meters measure the time it takes for ultrasonic pulses to travel upstream and downstream in the flow stream.

Ultrasonic clamp on（Non-Invasive Fluid Monitoring） flow meters readings are altered by acoustic properties of fluids and impacted by density, viscosity, temperature and suspended particulates, all dependent on the type of flow meter. 

Ultrasonic flow meters are commonly used in a variety of applications, including water and wastewater treatment, oil and gas production, chemical processing, and HVAC（BTU） systems. They are known for their non-intrusive installation, high accuracy, and ability to measure a wide range of fluid types. Overall, ultrasonic flow meters are a versatile and reliable option for measuring flow rates in various industries.

Understanding the Micro Magnetic Inductive Flow Meter for Ultra Low flow

图片
Introduction A magnetic flow meter, also referred to as a mag meter or an electromagnetic flow meter, is a device that measures the flow rate of conductive fluids using Faraday's Law of electromagnetic induction. This type of flow meter is widely used in various industries including water treatment, chemical, pharmaceutical, and food & beverage. How does a Magnetic Flow Meter Work? The working principle of a magnetic flow meter is based on Faraday's law of electromagnetic induction. According to this principle, when a conductive fluid flows through a magnetic field, it generates a voltage which is directly proportional to the flow velocity. The generated voltage is then measured by electrodes attached to the flow tube. As the fluid's velocity changes, so does the voltage. By measuring this voltage, the flow meter can accurately calculate the flow rate. Key Features of the Unique Magnetic Flow Meter To cater to the different needs of industries, magnetic flow meters come
