1. 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 measuring the temperature difference. At the same time, the temperature sensor can also directly output the actual temperature of the Na Shan fluid. -Advantages: Direct measurement of mass flow rate without additional temperature and pressure compensation, fast response speed, and the ability to measure extremely low flow rates of fluids - Limitations: Only applicable to gases or clean liquids, sensitive to changes in medium composition - Common scenarios: compressed air measurement, combustion gas flow control 2 The vortex flowmeter with integrated temperature sensor relies on the Karman vortex principle to measure the fluid volume flow rate. The manufacturer will integrate a platinum resistance temperature sensor inside the probe or body to synchronously detect the fluid temperature. It can simultaneously output instantaneous volume flow rate during excavation and fluid temperature, and can also calculate standard volume flow rate or mass flow rate after temperature compensation through built-in algorithms. -Advantages: Strong universality, adaptable to multiple media, w Working principle of thermal flowmeter

ide measurement range, good stability - Limitations: Sensitive to pipeline vibration, weak signal in low flow rate environments - Common scenarios: steam trade measurement, gas/liquid flow monitoring in industrial processes 3 Some high-performance models of time difference ultrasonic flow meters with temperature detection use the time difference between the propagation of ultrasonic waves in both forward and backward directions to calculate volumetric flow rate. Some measurement probes have built-in temperature sensors, while others estimate medium temperature based on the correlation between ultrasonic propagation speed and temperature. It can simultaneously output volumetric flow rate and fluid temperature (or estimate temperature). -Advantages: Non contact measurement, no pressure loss, suitable for flow detection of large-diameter pipelines - Limitations: There are certain requirements for the purity of the medium and the content of internal bubbles, and models with built-in temperature measurement function are relatively expensive - Common scenarios: heating/cooling water systems, raw water/sewage flow measurement 4 The temperature pressure integrated Litoba flowmeter is composed of a flow sensor, a temperature sensor, and a pressure transmitter. It can synchronously measure the mass flow rate and volume flow rate of liquids, gases, and vapors, and output fluid temperature, pressure, and medium density. The flow rate, temperature, and pressure are measured at the same point, with reliable accuracy and easy installation and maintenance. 5. The integrated display temperature pressure compensation vortex flowmeter integrates the flow sensor, temperature sensor, pressure transmitter, and flow calculator into one, and co
