  • Panels installed without tools, using 1/4-turn fasteners.
  • Can sample from pressurized lines.
  • Higher initial velocity than peristaltic and vacuum type samplers.
  • Standard lift exceeding 40’ — customized lift to 80’.
  • Maintenance-Free Design for long term, trouble-Free operation.
  • All BVS Automatic samplers meet ASTM D3370-76, Page 29.1, Recommended methods for proper sampling.
  • All BVS Automatic samplers carry a “Two Year Warranty” on parts and labor.
  • Samplers are available as NEMA I, NEMA IV and NEMA XII. Other styles available to meet your individual specification or requirements.
  • BVS samplers do not use suction as used by peristaltic or vacuum type samplers as this concept changes the solubility of the liquid by disturbing the gas/liquid balance. For this reason, suction type samplers should not be used when measurements to be made concern dissolved gases such as oxygen or carbon dioxide.
  • U.S.A. Made in Honey Brook, Pennsylvania.
  • Fully ventilated and heated cabinets with control thermostats.
  • Free technical advice is always available.

Pumps Employing suction…

Bulletin: The ASTM addresses "taking the sample" with this statement...
"Because pumps employing suction principles disturb the gas-liquid balance, use a submersible-type pump for pumping samples from open bodies of water whenever the measurements to be made concern dissolved gases such as oxygen or carbon dioxide.
(ASTM D3370-76 P 29.1)

All BVS liquid samplers utilize the flooded-suction concept of operation. With the sampling probe or pump submerged in the liquid to be sampled, liquid enters the sampling device by gravity, thereby giving a true representative sample of the liquid at that particular strata. The use of peristaltic or vacuum pumps, the suction concept of operation, does not give a true representative sample of the liquid that is being sampled. The use of suction changes the solubility of the sample by changing the gas/liquid balance. This change in solubility makes it impossible to get accurate measurements of dissolved gases.
