Detectronic Model 606 Manual Verified

Ensure the face of the transducer is perfectly parallel to the liquid surface. A tilt of even 2 degrees can weaken the return echo by 50%.

Like all ultrasonic sensors, the Model 606 has a "dead band" (usually the first 12–18 inches from the sensor face). Ensure the maximum liquid level never enters this zone, or the sensor will provide "lost echo" errors. detectronic model 606 manual verified
