Background & Challenge A customer in New Zealand wanted to use a TDLAS200A pumped methane sensor as a flow-through online monitor for the off-gas of a bioreactor. The reactor works at ambient temperature and pressure, the off-gas flow is about 1 L/min, and the gas composition changes over a run — it starts as methane

A customer wanted a KUS550 ultrasonic level sensor to control a supply pump from the tank level: the pump starts when the tank drops to a low level and stops when it refills. Two things had to be got right — the sensor must not be immersed, and the pump must not be cycled on a single threshold, which would make it start and stop repeatedly while the level sits near that value.

Background & Challenge A marine aquaculture operation in Korea needed closed-loop dissolved oxygen (DO) control for its breeding ponds. The requirement was specific: hold DO at a defined target — the customer used 1 mg/L as their example — and use that threshold to drive a nitrogen (N₂) solenoid valve, opening the valve whenever DO

A customer needed to measure the water level in a tank continuously, without putting an instrument into the water. Contact-type devices — floats and immersed probes — foul, corrode, or jam over time, and any of these turns into a maintenance call. The requirement was therefore a non-contact measurement of the water surface, mounted above the tank.

A customer installed a KUS640 integrated ultrasonic level sensor on a water tank. After installation, the instrument did not read the correct level: it displayed a plausible-looking number, but the value did not agree with the actual water level in the tank. A reading that looks reasonable is harder to spot than an obvious fault, which is what made this case worth recording.
