High temperature flow meters are instruments that measure flow rates at higher temperatures. For industrial measuring instruments, different types have their own corresponding high-temperature ranges. For example, a thermometer ranges from 1500 to 2000 ℃ as the high temperature range. For valves such as control valves and on/off valves, when it comes to high temperatures, it refers to temperatures above 400 to 500 ℃. The flow meter also has different high-temperature ranges specified according to the different principles and structures. The current practical upper limit for industrial temperature is around 540 ℃ for differential pressure flow meters of throttling mechanisms, around 200 ℃ for volumetric flow meters, and around 400 ℃ for area flow meters.

High temperature liquid flowmeter has advantages: no moving parts, no zero drift, high precision, long life, wide range, small flow, high temperature, low temperature, high pressure, negative pressure, antimagnetism, earthquake resistance, interference resistance, impurity resistance, blockage prevention, high viscosity, strong corrosion (sanitary type), no leakage point, especially in stability, applicability, repeatability, it has superior performance, and is a perfect flowmeter that surpasses quality and essence, Gas, liquid, and steam flow meters. It is well applied in flow measurement in various fields such as steel, oil, natural gas, electricity, ceramics, coal to oil, papermaking, chemical industry, energy, food, environmental protection, water conservancy, etc. The sensor does not come into contact with the tested medium, there is no component wear, and it is safe and reliable to use. The dry calibration method can be used on-site, that is, the weight hanging method. Single click operation can complete calibration, with multiple installation methods to choose from, such as online insertion, low installation cost, integrated temperature and pressure compensation, direct output of quality or standard, anti-interference, strong resistance to impurities, an
