Model 502 Suspended Solids Meter
The Model 502 Suspended Solids Meter measures suspended solids in wastewater and industrial processes using ultrasound. The meter reads concentrations and suspended solids that are too thick for optical turbidity meters. The meter is not affected by colour.
Features
- Not sensitive to color
- No optics to foul
- Push button calibration
- Dynamic damping
- Ultrasonic self-cleaning
Operation
The Suspended Solids Meters use the attenuation of ultrasound to measure the concentration of sludges and slurries that are too thick for optical methods. Markland`s meters operate in the region between turbidimeters and nuclear gauges.
The sonic pulse passing through clear water returns a strong echo and the meter reads zero. Suspended Solids absorb some of the sonic energy making the echo weaker and the meter then reads the % suspended solids of the slurry.
Technical Advantages
Ultrasonic attenuation can measure the density and concentration of sludges and slurries that are too thick for optical turbidimeters. Sonic vibrations help keep sensors from fouling and color is not important. Ultrasonic transducers contain no hazardous nuclear material and there is no inherent source decay to cause drift. Simplified microprocessor assisted pushbutton calibration locks calibration parameters into permanent non-volatile memory. Automatic dynamic damping adjusts for non-homogeneous material such as sewage sludge. Advanced digital self-diagnostics greatly simplify debugging. Ultrasonic Suspended Solids Meters bridge the gap where optical systems dont work and where the cost of nuclear systems is not warranted.
