The main purpose

It is suitable for the measurement of the flow velocity of water flowing through the catheter in a medical catheter under a constant static pressure head. It can also be used to determine the flow velocity of other rigid or semi-rigid fibers that are tubular materials and the water flowing through the catheter.

Instrument characteristics

1. With closed circulating water bath;

2. Equipped with a measuring cylinder to measure the effluent volume of the catheter, with an accuracy of ±1%;

3. The working environment temperature of the instrument must meet (20±2)℃;

Technical index

1. Reagent: distilled water or deionized water;

2. Constant liquid level container provides liquid flow rate (525±25) mL/min, and provides (1000±5) mm height static pressure head;

3. Liquid outflow time: 30s;

4. Power supply: 220V, 50Hz.
