4. Regulation Use
Any use of the Bypass level Indicator, model: NBK, which exceeds the
manufacturer’s specification, may invalidate its warranty. Therefore, any resulting
damage is not the responsibility of the manufacturer. The user assumes all risk for
such usage.
The NBK Bypass Level Indicator is used for continuous measurement, indication,
and monitoring of liquids in tanks, vessels, reservoirs, basins etc. The indication
occurs via a magnetically coupled roller indicator.
4.1 Bypass Measuring Tube System
The bypass tube is attached at the side of the vessel with a connecting flange or a
threaded pipe. The installation position is always vertical. The NBK should only be
used for liquids with the medium density specified on the nameplate. Otherwise the
indication will deviate (float too high or submerged).
Vessel inner pressure and medium temperature should not exceed the specified
maximum values, as this can lead to the destruction and malfunction of the bypass
system. It is imperative that the materials used are compatible with the liquid being
measured.
Proper operation is also impaired by:
high degree of soiling
suspended solids
crystallisation
ferrite particles
4.2 Electrical Limit Switches NBK-R
The optional electrical limit switches serve to signal a preset level.
4.3 Transmitter 00T
A magnetostrictive transmitter can be mounted outside the bypass tube to
teletransmit the level. A continuous standard signal of 4-20 mA is output by means
of a fitted transmitter.
