We are pleased to announce that after extensive testing and effort NIVELCO’s
series with dual compartment aluminium housing awarded first FM (Factory Mutual) and CSA (Canadian Standards Association) Explosion Proof Certification required by the North American markets.
Adjustment, programming: With local display/programmer module, remote HART programming
Mounting: On top of the tank. Sshould not be mounted in the middle of the tank or in the vicinity of the filling place or the outlet of the tank. The distance between the sensor and the tank wall should be at least 200 mm. The antenna face should be parallel to the medium surface within ± 2-3°. The instrument should be protected against direct sunshine.
Housing material: Plastic (PBT), Paint coated aluminium or Stainless steel
Material of wetted parts: Horn, Parabolic: 1.4571 (316 Ti) stainless steel; enclosure: PP, PTFE
Operating principle: The operation of the non-contact microwave level transmitters is based on the measurement of the time of flight of the microwave burst. The propagation speed of of the emitted linearly polarized microwave impulses is practically the same in air, gases and in vacuum, independently from the process temperature and pressure, so the measured distance is not affected by the physical parameters of medium to be measured. The time of flight of the reflected signal is measured and processed by the electronics, and then this is converted to distance, level or volume proportional data.
APPLICATION CONSIDERATIONS :
Suggested applications: Water and wastewater, Power generation, Food and beverage, Pharmaceutical, Chemical industry. For mid/ large-size vessels.
Measurable mediums: Liquids and slurries in general
Advantages: Easy installation due to small antennas. The rotation of the polarization plane can minimize unwanted false reflections. The enclosed antenna versions can be replaced without removing the antenna enclosure from the process. 99-point linearisation.
Special applications: Level measurement through plastic tank wall. Sanitary types for meeting high hygienic requirements.
Application restrictions: In some instances (e.g. disturbing reflections, steam or gas condensation) the maximal measurement range might decrease by 50 %! The relative dielectric constant (εr) of the medium should be more than 1.4 in case of parabolic design, or it should be more than 1.9 with horn antenna types.
2016 - Konstanca, SARGEANT MARINE ROMANIA S.R.L., Románia
The end-user SARGEANT MARINE ROMANIA S.R.L. is an England-based company having leading role in the Romanian road construction industry for nearly 20 years considering the amount of produced bitumen. The company’s facility is located in Constanța in the coast of the Black Sea where the bitumen is stored in 7 high capacity (9000 m3) tanks.
The measurement task was the following:
Continuously measure the stored volume in the tanks
Temperature measurement in three points inside the tank
Providing high fail-safe alarm with sound and visual indication
Local displaying of the measurement data
Collecting and logging the data in a central computer
Volume correction based on the measured temperature
2015 - Animal protein processing plant, Lins, Brazil :: Distributor: NIVETEC
JBS is a global leader in animal protein processing, owner of beef, pork and lamb, poultry and leather processing plants, in addition to feedlots. It also operates in the segments of cleaning and hygiene products, collagen, can making, casings, biodiesel, vegetable, recycling and transport. Headquartered in Sao Paulo and foothold in 22 different countries, the company has more than 185,000 employees in production platforms and sales offices.
The PiloTREK level transmitters provide highly reliable level measurement in the city of Lins in Sao Paulo state, where 16 cylindrical tanks with 16 m (52.5 ft) height need to be measured with high accuracy. The storage tanks – which are equipped with PiloTREK WGP-140-4 type Pulse Burst Radars with PP encapsulated DN40 (1 ½”) antenna – contain water based emulsion of vegetable fats. The process temperature inside the tanks is 60 °C (140 °F) and the level never goes under 25%.

2013 - Hartmann Hungary, Ács
The main product of Hartmann Hungary is paper egg tray which is manufactured from recycled paper waste. The pre-processed paper waste should be cleaned from the painting materials mainly for optical and for chemical protection reasons. This so-called „deink” process use Hydrogen peroxide which is stored in a large outside plastic tank. The continuous level measurement is solved with a PiloTREK Pulse Burst Radar, high / low fail safe alarm is provided by NIVOSWITCH level switches and the temperature should be also measured. The challenging measurement conditions are high temperature and strong condensation, this is the reason that the PiloTREK level transmitter is equipped with PP antenna enclosure.

2013 - GlaxoSmithKline, Gödöllő, Hungary
GSK is one of the most well-known medicinal chemistry and vaccine producers all over the world. In the Hungarian facility of GSK they use CIP Cleaning-In-Place / SIP Sterilization-In-Place processes in order to provide the required high purity for the medicinal production. These cleaning processes use low concentration acid materials which is in this case is sulphuric acid, stored in 1m3 (35.3 ft3) moveable vessels. The level measurement of the removeable sulphuric acid storage tanks is solved by a PiloTREK Pulse Burst Radar equipped into the openable top over the tank. The speciality of the application that the PiloTREK Pulse Burst Radar measures the level through the plastic tank wall.
A creamery in the Czech Republic produces milk products and uses some types of corrosive chemicals for example in the cleaning process where the level measurement of these mediums are really challenging
for all instrument manufacturers. The chemicals are stored in 2 closed 1 m3 (35.3 ft3) sized plastic tanks.
The customer’s demand was to continuously measure the level
of the chemicals using non-contact radar measurement through
the plastic tank wall.
The subject of the measurement task is 160 °C (320 °F) bitumen in order to proper stock management. The level in the 7.9 m (25.9 feet) high tank is measured by a PiloTREK WHS-180-4 high temperature type unit. The PiloTREK is connected to a data logging capable MultiCONT PRD-210 process controller unit to monitor the measurement data.
