Markland Specialty Engineering Ltd. products

Markland’s handheld sludge blanket level detector - The Sludge Gun - makes it easy to check the liquid-solids interface level in diverse applications, including septic tanks, ponds, lagoons. Simplify routine monitoring for regulatory compliance, and help to prevent carryover and unnecessary pumping or dredging. Compact and weatherproof, this portable sludge level detector is ideal for use from catwalks or boats.

Markland’s simple and effective single point monitoring and automatic control to maintain your preferred sludge blanket and supernatant interface level.

This is Markland’s most comprehensive sludge blanket level detector, offering automation of desludge pumps at both high and low set points and providing a LED readout, yet versatile enough for use in obstructed or constricted areas.

Available as a throw-in probe or an inline spoolpiece, this meter uses attenuated ultrasound, making it an ideal choice for use when concentrations are too thick for optical meters yet nuclear metering is unnecessary.

This simple, inherently explosion-proof sampling system has virtually no moving parts to break down. Sample automatically and easily, even up high lifts, over long runs and in freezing temperatures.
