Nivelco
NIVELCO is a Hungarian maker of level measurement instruments, based in Budapest. Its roots go back to a telephone equipment business founded by Endre Szőllős in 1939, and the company specialised in level measurement as NIVELCO in 1982. In 1989 it launched the first compact ultrasonic level transmitter that combined sensor and electronics in one unit. Seven Star LLC lists the Nivelco EasyTREK ultrasonic level transmitter and supplies Nivelco level instruments to water, wastewater and process sites in Oman. EasyTREK is the integrated ultrasonic unit in the range, with transducer and electronics in one housing, mounted above the liquid without touching it.

Nivelco product families
Nivelco names its families by principle: EasyTREK and EchoTREK for ultrasonic level transmitters, MicroTREK for guided wave radar, PiloTREK for non-contact radar, and NIVOSWITCH among its level switches. An ultrasonic transmitter works from the echo time between the sensor face and the surface, so foam, vapor and the nozzle length all affect the choice of model and frequency.
Ordering Nivelco instruments: what we need
Send the full order code from the nameplate, which fixes the measuring range, transducer material, process connection, output and any hazardous-area version. For a new point, give the medium, tank height, nozzle size, process temperature and pressure, the required output (for example 4-20 mA with HART) and the area classification. This applies to inquiries from anywhere in the GCC.

FAQ
Questions about Nivelco
Common questions about Nivelco equipment, part numbers and supply to Oman and the GCC.
01How do I identify my Nivelco EasyTREK model?
Read the order code on the nameplate. Nivelco codes combine a letter group for the family with digits and letters for range, transducer material, process connection, output and approval. Because several EasyTREK versions share the same appearance, send the whole code and the serial number, or a clear photo of the nameplate, so the identical version can be confirmed.
02What is the difference between Nivelco EasyTREK and EchoTREK?
Both are ultrasonic level transmitters. Nivelco describes EasyTREK as the integrated type, with the transducer and the processing electronics in one single IP68 housing. EchoTREK is the compact transmitter type, with a 4-20 mA output and HART as an option. Ranges, materials and outputs differ by version, so the choice is checked against the manufacturer's datasheets for the tank and medium in question.
03How does a NIVELCO EasyTREK work?
EasyTREK sends ultrasonic pulses down to the liquid or solid surface and times the echo. The transmitter converts that time into level, distance or volume and outputs 4-20 mA with HART.
04Is Seven Star LLC a distributor of Nivelco?
No. Seven Star LLC is an independent industrial supplier in Muscat and is not a distributor or agent of Nivelco. We source Nivelco level instruments through commercial channels, check the model or order code against the manufacturer's documentation, and provide the manufacturer's datasheet and the certificates the manufacturer issues with the order on request.
05What should I send for a quotation on a Nivelco level transmitter?
Send the nameplate order code for a like-for-like replacement. For a new application, send the medium, whether foam or vapor is present, the measuring span, tank and nozzle dimensions, process temperature and pressure, the output signal, the supply voltage and the area classification. Mention any certificates you need from the manufacturer.
