Water Sampler and Wastewater Sampler Support | Campbell Scientific Samplers Flow Pacing / Configuring 4-20 mA Input for Campbell Scientific Water Samplers Learn how to program Campbell Scientific vacuum water sampler to use a 4-20 mA input for pacing and timed-step sampling sequence. Programming the PVS, CVS or BVS sampler controller via keypad to accept 4-20 mA inputs. https://youtu.be/ILu3tGY7SHU Flow Pacing, Pulses per sample calculation and Wiring Examples for Flow Meter or other 4-20 mA input: Campbell Scientific Vacuum Sampler Troubleshooting How to troubleshoot a water sampler that will not pull a sample into the metering chamber. Check the following: * The pinch valve for operation * The sampler chamber for leaks * The intake hose for leaks * Meter chamber lid O-ring * The pressure on intake hose with a vacuum gauge https://youtu.be/AH7LhivmdcA Campbell Scientific Sampler Controller Troubleshooting If the Campbell Scientific water sampler controller keypad is unresponsive or the display is incorrect: * Remove the sampler controller cover * Locate and press the reset button * Replace the internal battery when it measures less than 2.6 Vdc * Check the power coming into the controller. It should be 13 to 14 Vdc * Reprogram the controller if required * Change the purge time if required https://youtu.be/tM86Yn4oOdA Power Supply and Pump Troubleshooting If the Campbell Scientific Sampler Pump or Power Supply Troubleshooting: * Access the sampler power supply and pump * Check the voltage in and out * Check for pump leaks * Determine if pump electrical brushes and wiring need to be replaced * Locate the pump diaphragm and determine if it needs to be replaced https://youtu.be/0kVkoZrbKfg Manuals Campbell Scientific CVS4200 and BVS4300 Sampler Manual Campbell Scientific PVS5120 Sampler Manual
We receive a lot of questions about Vacuum vs Peristaltic Portable Samplers for Water, Wastewater, Stormwater and Runoff Monitoring. We're looking today at three of the leading providers of water samplers and sampling equipment. These water samplers use different sampling technologies and pumps to get the job done: ISCO 6712 vs Campbell Scientific vs Hach Sigma SD900. See the full comparison table of Peristaltic Vs Vacuum Portable Samplers. Portable water samplers use either peristaltic pump or vacuum pump technology to obtain the liquid samples. Both portable sampler pump technologies are designed to quickly move most fluids from the source into the water sampler. Let's take a closer look at Portable Vacuum Samplers vs Portable Peristaltic Samplers So what do you see as the main differences between vacuum based samplers and peristaltic samplers? What advantages are most important for you with vacuum samplers? What are the most important advantages of peristaltic samplers for you? Let us know in the comments below.

Reliable Wastewater Effluent Sampling Wastewater effluent sampling can be challenging for treatment plant operations. Every wastewater sample is valuable. Missed samples and failures can lead to loss of data in reports, overtime for grabbing additional samples and even compliance issues. Vacuum pump water sampling technology offers a significant improvement over peristaltic pump technology for water sampling. The Problem with Peristaltic Samplers Peristaltic type outdoor water samplers have traditionally had peristaltic pump tubing failure or peristaltic pump roller failures. The second most frequent issue encountered with outdoor samplers are refrigerator failures. This particular municipal wastewater plant in Ohio had experienced multiple water sampler failures in the past and was looking for something simple and more reliable. The Solution with Vacuum Based Wastewater Effluent Samplers These BVS 4300C water samplers from MCE Process and Campbell Scientific replaced the failed ISCO Automatic Water Sampler units at a wastewater plant in Ohio. This water reclamation facility really wanted a more reliable sampler for wastewater influent and wastewater effluent. The Campbell Scientific BVS4300C Stationary Automatic Water Sampler was the wastewater sampler of choice. The reliability of vacuum wastewater samplers along with the reduced maintenance was the real determining factor.The BVS4300C provided the stationary automatic wastewater sampler needed in a outdoor heavy duty package. Why Go With Vacuum technology to replace the Peristaltic ISCO sampler? Vacuum Samplers have clear technology benefits over peristaltic pump samplers Higher Accuracy and Consistent Sample Volumes Rapid Transport velocities = more-representative samples Less disturbance of sample No roller contact with tubing = less-frequent maintenance Cross contamination of the samples are greatly reduced by a positive pre and post purge Get started with wastewater effluent samplers Discover More Vacuum Sampler Advantages Learn more about wastewater sampling at http://mceprocess.com/samplers/
