(be the first to review)

In-plane Water Flow Rate Test Apparatus,also named ASTM D4716 Geosynthetic In-plane Water Flow Rate Tester or Geosynthetic In-plane Water Flow Rate Tester which is used to determine the horizontal permeability of geosynthetic materials under constant water flow conditions .It is  Easy to use this machine .

In-plane Water Flow Rate Test Apparatus DW1380

In-plane Water Flow Rate Test Apparatus is applied to determine the in-plane flow rate per unit width and hydraulic transmissivity within the manufactured plane of geosynthetics under varying normal compressive stresses and standard hydraulic gradient using a constant head. Aggregate thickness of the test specimen and rubber sheets loaded on base: 20~100 mm , For better experimental operation, it is recommended to place the instrument on a cement workbench at a certain height depended on heights and operation habit of operators (the recommended height of workbench is about 450mm).

We provide reasonable price and high quality In-plane Water Flow Rate Test Apparatus. All of testing instruments manufactured by FYI are well-known throughout China . Of course we can discuss with customer and help customer to customized the machine .

Follows are In-plane Water Flow Rate Test Apparatus

  • Conform to different standards, such as GB/T 17633, ASTM D4716 and BS EN ISO 12958;
  • Adjustable pneumatic pressure of 0~600Kpa;
  • Elevating screw rod to manually and continuously adjust head difference up to 400mm with water-level scale display.

Application

Application of In-plane Water Flow Rate Test Apparatus 

In-plane Water Flow Rate Test Apparatus is applied to determine the in-plane flow rate per unit width and hydraulic transmissivity within the manufactured plane of geosynthetics under varying normal compressive stresses and standard hydraulic gradient using a constant head.

Supporting frame composed of aluminum alloy profiles with square cross-section is used to support the main body, reservoirs, overflow elevating device and water storage tank.

In-plane Water Flow Rate Test Equipment complies with BS EN ISO 12958-2010, ASTM D4716-2007 , GB/T 17633-1998, SL/T 235-9-2012 etc international and retailer standards.
