Overview

The BVS4300C is a stationary water sampler designed for outdoor use. It is housed in a protective steel enclosure to resist harsh conditions. The sampler uses reliable, long-lasting, vacuum technology. This sampling method results in faster sample draws and less disturbance of the sample contents. There is also less wear on the tubing, resulting in less frequent maintenance.The BVS4300C is a composite sampler, with all samples combining into a single container. The BVS4300D is a discrete sampler and places each sample into a separate container.

Vacuum technology benefits over peristaltic pump samplers:

  • Accurate sample volumes
  • Rapid transport velocities mean more-representative samples
  • Less disturbance of sample
  • Minimal wear on the tubing, resulting in less-frequent maintenance
  • Reduced cross-sample contamination

Detailed Description

The BVS4300C is an outdoor stationary water sampler that deposits its water samples into one container. This sampler is designed to handle extreme environments. It has a corrosion-resistant steel enclosure with a locking door and bolted-down instrument panel.

The BVS4300C uses an external vacuum pump to draw water through intake tubing, instead of the traditional peristaltic pump that induce flow by squeezing flexible tubing. Advantages of the vacuum pump method include faster sampling rates, better vertical lifts, longer sampling distances, and less maintenance. Because the vacuum method disturbs the water samples less, they better represent the original water solution, especially if the solution has high concentrations of suspended solids. To prevent cross contamination, the sampler use air pressure (up to 28 psi) to purge the tubing of excess water.

The controller that comes with the BVS4300C can accept a pulse input (e.g., rain gage), a 4 to 20 mA signal (e.g. flow meter), or initiate a sample on a timed basis. The sampler can also be interfaced with our dataloggers.  Our dataloggers can measure nearly any turbidity, water level, or hydrometeorological sensor, as well as control the sampler based on time, event, or measured conditions.

Compatibility

The controller that comes with the BVS4300C can accept a pulse input (such as from a rain gage) or a 4 to 20 mA signal (such as from a flow meter), or it can initiate a sample on a timed basis. The sampler can also be interfaced with our data loggers. Our data loggers can measure nearly any turbidity, water level, or hydrometeorological sensor, as well as control the sampler based on time, event, or measured conditions.
