LFY-710 Catheter Flow Meter

Invention Patent: ZL 2015 1 0405837.9 
Main purpose/Use 
It is applicable for measuring the flow rate of water passing through the conduit under a constant static pressure head, and can also be used to measure the flow rate of water flowing through the conduit when other rigid or semi-rigid fiber tubular materials are involved. 
Technical indicators 
1. It is equipped with a closed-loop constant-temperature water bath; 
2. Equipped with high-precision sensors to measure the quality of the effluent from the tube, with an accuracy of ±1%. 
3. The operating temperature of the instrument must be within the range of (20 ± 2)℃. 
4. Utilizing computer control, it features a fully Chinese interface and has a high degree of automation. 
5. The data is processed by the computer and has a printer interface. It can also display the test data directly. 
6. Reagents: Distilled water or deionized water; 
7. The water temperature of the constant temperature water bath is 22℃ ± 2℃. 
8. The constant liquid level container provides a liquid flow rate of 525 mL/min ± 25 mL/min, and a static pressure head of 1000 mm ± 5 mm. 
9. Liquid outflow time: 30 seconds; 
10. Sensor range: 0 - 500g, measurement accuracy: ±1% 
11. Power Supply: 220V, 50Hz.
