Designing and manufacturing control and monitoring instrumentation for water, wastewater and process industries since 1967. Sludge Blanket Level Detectors - handheld and fixed installation detectors help maintain preferred levels of slurry or sludge and prevent carryover. Automate de-sludge pumps to operate only when necessary. Suspended Solids Density Meters - provide real-time readings of total suspended solids (TSS) and automate underflow pumps to help optimize dosing and feed density. Inline meter and throw-in probe sensors are unaffected by colour of fluid/particulates. Automatic Composite Sampling Systems - explosion-proof samplers move samples even up high lifts, over long runs, or in freezing temperatures.
