Installation guidelines for SB mechatronic flow meters

The SB family of sensors are easy to apply with few restrictions. Details can be found in the operating instructions on the product datasheet page and are summarized below.

The SB comes mounted on a non-return valve, meaning the flow can only move in one direction. At higher system pressure, the non-return valve seals more tightly than it does at lower system pressure. We cannot guarantee 100% sealing as a check valve would, but it is quite possible the seal may be adequate to prevent backflow.

Install the sensor following the flow directional arrow cast into the valve assembly.
Straight pipe runs into and out of the sensor are not required. It is unaffected by flow turbulence.
The sensor head can be rotated 360° for easy viewing.
Install a 200-micron filter on the inlet side of the sensor, especially when the media contains dirt or other particles.

Should the sensor be clogged with dirt, it may be disassembled and cleaned using the following procedure.

Unscrew sensor head (1).
Remove float (2) and spring (3).
Clean float as required.
Clean inside housing with cloth or compressed air.
Before reassembly, inspect o-ring (4) and replace as necessary. Apply appropriate grease.
Reassemble and tighten the sensor head with a torque of 10 Nm.
To restore the measurement accuracy after reassembly, press the float (6) with something non-magnetic (5), like your finger and hold for at least 2 seconds.

Due to the magnetic technology used in the measuring principle, observe the following mounting distances.

Distance between the sensor and ferromagnetic materials	> 30 mm (1-1/4”)
Distance between the sensor and constant / alternating fields	> 500 mm (20”)
Centerline to centerline distance between sensors for side-by-side mounting	> 50 mm (2”)
