Geotextile Vertical Permeability Tester

Instrument use:

Used for testing water permeability of geotextile.

Standards:

GB/T15789, ISO11058 etc.

Product features：

1. The flow can be controlled to: 5L/min, can measure the permeability of single layer geotextile;

2. With flowmeter, can control the head pressure difference;

3. The water from the sample below the upward through, no drop, will not form bubbles;

4. The whole machine adopts imported 304 stainless steel; The work table adopts imported special aluminum, sandblasting oxidation treatment, rust and corrosion prevention, the whole machine is relatively light;

Technical parameters：

1. The equipment is used to measure the velocity index and other permeable characteristics of the geotextile and its related products through which the water flows vertically through a single layer and cannot be loaded under constant water head;

2. The machine is made of imported 304 stainless steel, the table is made of imported 304 stainless steel plate, rust and corrosion prevention;

3. Different ranges can be selected according to the sample permeability. There are four 600mL /min flow meters, suitable for the sample with small permeability; Another flow device can meet 5L/min, used for the sample with large water permeability; Head pressure difference can be compensated;

4. Built-in water tank capacity as far as possible to ensure that the head pressure difference is not flushed; Water is injected from the bottom of the sample through a static flume to remove bubbles in the water and reduce the test error.

5. During the test, keep constant water head on both sides, accurate to 1mm;

6. The maximum head pressure difference: 300mmH2O;

7. Clamping sample inside diameter: ф 50mm±0.1mm;

8. Can be tested sample thickness 0.1 ~ 10) mm;

9. Flow range 0 ~ 5) L/min;

10. Measuring cylinder: 1000ml (measuring accuracy 10ml);

11. Water level indicator: indexing value 1mm;

12. Overall size: 1200×650×1900mm (L×W×H);

13. Weight: 85Kg;

Configuration list：

1. host machine

2. One 1000ml measuring cup

3. One product certificate

4. One copy of product instruction manual

5. One delivery note

6. One receipt of acceptance

7. One product album
