NBK-19 Bypass Level Indicator
Brand: KOBOLD Instruments, IncThe KOBOLD bypass level indicator model NBK-19 is based on the simple function principle of cable and deflection pulley.
The tank float, made of PPH or stainless steel, is moved up and down by the medium depending on the level in the tank. This tank float has a counter-float (counterweight), which moves correspondingly in a transparent PVC tube in dependence on the level.
The floats are connected to one another by means of a cable over 2 deflection pulleys. The magnetic counter-float has a ring marking for reading the scale on the bypass PVC tube.
