Product Introduction
Liquid Interface Measurement System
Liquid Interface Measurement System
- Particular gases are able to be stored as liquid state by means of high pressure in seamless cylinder.
- In case of liquefied gas state, vaporization and liquefaction takes place continuously. At that time, it maintains equality state due to the same reaction heat value.
- Applying local heat to a seamless cylinder for about 100 seconds, , it is possible to detect temperature difference at boundary between gas state and liquid state and its measured temperature value is able to be converted to residual gas quantity in the liquefied gas cylinder.
| Principal & Characteristic / Measurement Method |
Measurement Method | Characteristic |
|---|---|---|
| Load Cell Method | After disassembled all gas cylinders and Shall weight all cylinders respectively. | Very common method for measuring but it's required lots of time and cost |
| Radio-Activity Method | Using radioisotopes used with irradiated into gas cylinder | nRequired licensed person to handle the equipment. Measurement device is very expensive.(USD 10,000.00) |
| Ultrasound Measurement Method | Using ultrasonic wave by detecting the reflected wave | Unnecessary to accquire for handling license. Measurement device is very expensive.(USD 10,000.00). Unreliable due to large error of measurement data. |
| Liquid Interface Measurement System of NICEENTECH | Using temperature difference at boundary between gas and liquid state | It's possible to monitor the data in real time by using wire and wireless communication system with low cost |
