The new, „NIVELCO ACADEMY” project started in 2017. This project – mostly – contains videos that demonstrate our products’ operating principles, properties and application areas.
Our first video presents the NIVOMAG MK-200 series magnetic coupling level switch.
Short description: The NIVOFLIP is a magnetic level indicator for pressurized vessels containing liquids. The NIVOFLIP can be equipped with optional limit switches or with NIVELCO’s magnetostrictive level transmitter if point-level detection or continuous level transmission is required.
Operating principle: The liquid level in the bypass tube and the tank is equal. A float in the bypass tube incorporating a polarized magnet tracks the level of the liquid. The bi-coloured magnetic flaps serving as visual indicators by changing their colour as the float passes. The lower 100 mm (4inch) of the bottom section of the indicating bar has different colour providing for a visual error signal.
Mounting: On suitable connection flanges located on the side of the tank.
A feedwater tank needed a simple but reliable level control. During de-gassing process the water is heated to about 100°C (212°F) followed by ventilating the tank for reaching a close to atmospheric pressure. To provide for a complete indicator/ controller task, a NIVOFLIP bypass indicator is used here for displaying level aided by 3 pieces of MAK-100 switch units also strapped on the chamber doing the control task. Two of the switches control the filling procedure, the third takes care of overfill protection. In order to reduce heat loss the bypass chamber just as the tank itself is heat-insulated.

2014 - Steam accumulator, France :: Distributor: C2Plus
Steam is an important energy carrier for certain processes. In this application a pressurised tank containing hot water and steam provides for storing the energy needed. To control water level, the plant management was looking for a highly reliable MLI to replace their existing system of reed switches operated by a float tracking level in the bypass chamber. In the new system a NIVOFLIP bypass indicator is used for displaying level aided by MAK-100 switches strapped on the chamber doing the control task.

NIVOFLIP MAK-100 – 8 pcs
2014 - Steel producer, France :: Distributor: C2Plus
Prior to rolling the steel sheets to huge spools they are cleaned with demineralised water which is stored in a small vessel. The installed NIVOFLIP bypass level indicator has
550 mm (1.8 feet) flange to flange distance and the unit provides clearly visible optical display. The bypass chamber is equipped with
a NIVOTRACK magnetostrictive level transmitter which performs high accuracy level measurement
and displays the level on the SAP-300 plug-in display module and transmits the measurement
data to the central control room.
The bypass chamber is also equipped with 3 MAK-100 level switches performing high limit,
low limit, and low fail-safe level alarm indications.
2013 - A Hydro Project, South America :: Distributor: C2Plus
A 2x84 megawatt hydropower project located in one of the Latin American countries required a high resolution measurement solution for short (c to c = 200 mm (7.85 inch)) bypass tubes to control lubrication oil level. A NIVOFLIP was selected as optical indicator accompanied by a NIVOTRACK for providing accurate level transmission. Also strapped on the bypass tubes each, two pieces of MAK-100 level switches operated by the same float are taking care of low and high alarms.
NIVOFLIP MLB-105-0 – 12 pcs
NIVOTRACK MTL-505-2 – 12 pcs
NIVOFLIP MAK-100 – 24 pcs
