1. Vortex flowmeter | Technical points

The technical points of vortex flowmeter mainly include accuracy, repeatability, sensitivity, response time, zero drift, and range drift. The specific content is as follows: Accuracy: Accuracy, also known as precision, refers to the degree to which the measurement results of vortex flowmeter are close to the true value. Generally expressed as absolute error or relative sensitive bending pants error, absolute error=measured value - true value, relative error=absolute error/true value. Any type of flowmeter cannot accurately measure the true value of the measured parameter during measurement, and can only try to make the measured value as close to the true value as possible. In practical applications, the accurate standard instrument indication value is usually used as the true value of the measured medium. The difference between the indication value of the measuring flowmeter and the indication value of the standard instrument is the measurement error. The smaller the error value, the higher the reliability of the measuring flowmeter. Repeatability: Repeatability refers to the percentage of the difference between each measured value and the average value relative to the maximum scale range when the same vortex flowmeter is used for multiple repeated measurements under unchanged measurement conditions such as pipe diameter, medium flow rate, temperature, and pressure. This is an important indicator of the stability of the vortex flowmeter, which generally needs to be inspected during instrument operation and daily calibration. Sensitivity: Sensitivity refers to the degree of sensitivity measured by a vortex flowmeter. The ratio of the change in output of commonly used vorte

x flowmeters in the industry to the change in the measured parameters that cause these changes. The integrated vortex flowmeter with temperature and pressure compensation function can simultaneously measure temperature, pressure, and flow rate, and the sensitivity of multiple parameters often better reflects the performance of the flowmeter. Response time: When the bridge parameters of the measured medium change, the displayed value of the vortex flowmeter can only be accurately represented after a certain period of time. The time lag between this and the change in the measured parameters is the response time of the vortex flowmeter. Other instruments also have response times, some expressed as time constants, such as thermistor temperature measurement; Some are expressed in terms of damping time, such as measuring resistance with an ammeter. Zero drift and range drift: Zero drift and range drift refer to the percentage change of the average relative to the range after multiple measurements of the confirmed relative zero and maximum range of the vortex flowmeter.

2. Are there any instruments that integrate flow meters and thermometers together?

There are many instruments on the market that integrate flow meters and thermometers together. The following are common types of products and their characteristics.

1. Thermal mass flow meters are the most typical 2-in-1 instruments that work based on the principle of thermal diffusion.

. The sensor is equipped with heating elements and temperature detection elements, which take away heat when the fluid flows through. The fluid mass flow rate can be calculated by maintaining a constant temperature difference with the required heating power or directly measu
