Common Issues
Readings are inconsistent. The ultrasonic elements within the S6A are sensitive to electrical noise. They may have trouble reading correctly when located in areas with sizeable electrical interference or located near large motors and drives.
Readings are not accurate. A digital drawdown (or customer calibration) is recommended to ensure the most accurate readings. Perform a Digital Drawdown at the flow rate that is typically used at this flowmeter location. If the flow rate changes significantly due to process changes or seasonal flows, we recommend performing another Digital Drawdown at the new flow rate.
The Display reads “Poor or Low Signal”. Check that the chemical used is compatible with S6A. The S6A is dirty or contains debris and needs to be cleaned. Check “System” page of Blue-Central and note signal levels. Contact customer service.
The Display reads “Empty Tube” but the tube is full. The chemical may be incompatible with the S6A. The S6A ultrasonic sensors may not be working properly or there may be a poor wiring connection within the unit. Check “System” page of Blue-Central and note signal levels. Contact customer service.
Solution is leaking from the top or bottom fittings. Check to ensure o-rings are present and seated properly. Clean or replace, as necessary. Make sure S6A is not supporting piping, or that piping is misaligned with S6A causing stress on the top and bottom union fittings.
Electricals
The S6A will not power up. The S6A can be powered from the power supply or via USB connector. Check power supply connection (may require opening the unit to ensure proper power wiring. )
Blue-Central does not connect to S6A. Check that the USB connectors and cable are not damaged or worn. Use a USB-C to USB- A cable (USB-C to USB-C cables will not work.)
Calibration and Digital Drawdown
Digital Drawdown fails or won’t complete. The value chosen for Digital Drawdown is not within the range of the S6A. S6A1 calibration range is 50 ml/min – 5,000 ml/min, S6A2 calibration range is 500 ml/min – 10,000 ml/min. An excess of air bubbles or debris will cause the Digital Drawdown to fail. Ensure the solution is clean and free of air.
