For today’s environmental professionals, obtaining quality samples for low flow monitoring of groundwater sources is critical. If you are already using the Horiba W-22, you know how powerful a tool it can be for monitoring several different water quality parameters. But did you know that, with the addition of the optional flow cell, you can also measure water pumped using a low-flow peristaltic or other pump? The Horiba W-22 flow cell works with the W-22 instrument to allow you on the surface low flow monitoring of discharge water from a pump or other device.

How It Works

The Horiba W-22 flow cell is designed specifically for use with the W-22 water quality meter and an appropriate pump, foot valve or other low-flow sampler. Set up the pump as per the manufacturer’s instructions, and begin pumping at the desired rate. For low-flow sampling, between 0.1 and 0.5 liters/minute is ideal.

Remove the cap and seals from the flow cell, and gently place the Horiba W-22 meter’s sensor inside. The flow cell has been designed to snugly fit the W-22 probe. Please note the flow cell is not compatible with W-23 dual-sensor units.

Replace the cap and seals, and connect the pump to the flow cell input coupling. Confirm the flow rate by spilling effluent into a graduated cylinder for a set period of time. Multiply the amount effluent by the time to obtain the flow rate. Once the flow rate has been confirmed and the cell has been tightened, you can begin monitoring.

Precautions

The Horiba W-22 flow cell is fairly simple to operate as long as you are mindful of a few cautions:

  • Do not attempt to use the flow cell with anything other than a Horiba W-22 or U-22 water quality meter.
  • Make sure the pump tube is not bent or otherwise obstructed before use.
  • Do not use the flow cell for sampling anything other than water or a water solution.
  • Keep the flow cell upright during operation.
  • Be careful not to damage the probe sensor while installing it in the flow cell.
  • Never use organic solvents or a hard brush to clean the cell after use.

Advantages of Low-Flow Sampling

There are a number of reasons why low-flow sampling has become popular for several groundwater monitoring applications:

  • Low-flow samples are more representative of the contaminant profiles found at different depths.
  • Minimal disturbance produces less turbidity and fewer sample artifacts, improving accuracy.
  • Sampling is more consistent as stagnant and casing waters mix less.
  • Purge volume is lower, reducing disposal costs.
