Description

technical field [0001] The invention relates to a thermal monitoring system for a pool, in particular to a thermal measurement system and method for a pool device. Background technique [0002] At present, gas pressure sensors and liquid pressure sensors are commonly used in the world to extend into the fluid to measure the pressure of gas and liquid respectively. However, this kind of measuring device is limited by the range of the sensor and the temperature of the fluid. Different types are required for different ranges, accuracy and temperature requirements. sensor. [0003] The methods commonly used in the world to measure liquid level include glass tube method, differential pressure method, buoy method, inductance method, and ultrasonic method. The method needs to open a hole in the side wall of the lower end of the container, and there are safety hazards such as leakage; the differential pressure method is often used in normal pressure containers, which converts the p...

AI Technical Summary

Problems solved by technology

The flow rate of the fluid increases while the fluid passing through the resistance part generates a large pressure difference, so the flow rate can be measured by measuring the pressure difference through the resistance part, but the orifice flowmeter has a long straight pipe section requirement, which is generally difficult to meet, and the pressure The loss is relatively large; the vortex flowmeter is a velocity flowmeter, and the stability of the vortex separation is affected by the flow velocity distribution, which has certain requirements for the straight pipe section. To install a turbine flowmeter, the pipeline must have certain shock-absorbing measures. The stress-type turbine flowmeter uses a transistor as a detection sensor, and its service life is limited by temperature; the electromagnetic flowmeter is made according to Faraday's law of electromagnetic induction to measure conductive liquids. The instrument cannot be used to measure liquids with very low conductivity, nor can it be used at higher temperatures. At the same time, both vortex flowmeters and electromagnetic flowmeters will increase the difficulty of pipeline layout

[0005] At present, there is no general-purpose thermal measurement system that can use a set of devices to cover the measurement of two or more thermal parameters.
