2016 - Vilayat, Nirlat, Israel :: Distributor: Technomad Industrial Instruments and Control Ltd.
Nirlat is one of the largest and leading Israeli industrial companies specializes in the development, and manufacture paint, decorative paint, powder, surface preparation compounds and sealants. Nowadays, as part of Israel south region development, Nirlat’s factory is replacing old production lines with new ones including all level transmitters & switches.
Last year Zalakaros Thermal Spa set the aim to implement an advanced building management system using the most recent technology available. The launch of the project was planned in two stages. In the first stage a complete data logging and data analysing system has been implemented and then in the next stage the complete process automation system will be based on this.
The BMS is able to collect and evaluate the data of the following systems:
2015 - Flood monitoring using EasyTREK, Naryan-Mar, Russia :: Distributor: RusAutomatization
New flood monitoring system was installed in the town of Naryan-Mar in the Pechora River developed by RusAutomatization. The system is equipped with EasyTREK ultrasonic level transmitters providing continuous level monitoring of the river. In addition to the level transmitter the system also includes battery backups for the power supply and a MODBUS GPRS RTU data terminal, which transmits data directly towards mobile or computer network.
The data is carried by a packet-switched network and transmitted to the central server where the results of measurements are recorded and store into a database. The users can access to their own data easily via the Internet.
The user can specify the water limit values directly on the server and when the level values are reached the system sends SMS notifications to the specified mobile phone numbers. The system is able to send SMS notifications also when the external power supply is terminated or the batteries run out of power.
The measurement task was to continuously monitor the level in 10 outside lying cylindrical tanks where the highly flammable liquids are stored and to control the input and output batch of the stored products automatically.
The supplied ultrasonic level transmitters were the EasyTREK SPB-370-8 Ex with PVDF housing having 4-20 mA + HART output.
All the analogue 4-20 mA output signals of the EasyTREK transmitters are sent to a central PLC that monitors whether the tank was stocked with the right amount of chemical products and all measurement data are continuously logged.
2015 - Sewage works, Lebanon, USA :: Distributor: Aqua Technology Group
The wastewater operations for the City of Lebanon, Ohio had an existing flow meter that had failed after just two years of operation. They needed a reliable way to measure flow going across both
V-notch weirs and add flow pacing to the other process controls. The IP68 rated EasyTREK SPA-38N-4
integrated ultrasonic level transmitters are installed to a console above the basin. The measurement data is sent to the central SCADA system along with using the additional output of the MultiCONT to control the UV disinfection and their effluent wastewater sampler.
2015 - Brewery, Ohio, USA :: Distributor: Aqua Technology Group
The watewater of a new startup craft brewery is measured with open channel ultrasonic level measurement system. The facility in Ohio use a 4 inch Palmer-Bowlus flume with approach section equipped with EasyTREK SPA-39N-4 type ultrasonic level transmitter with and MultiCONT universal display and controller. The data is logged internally in the NIVELCO flow meter system and made available to the city council when required.
In the water / wastewater industry the reduction of the odour impact and the corrosion of the sewer system is an important task.
To prevent the formation of hydrogen sulphide gas, our partner Katalin Novum Ltd. has developed a chemical feed system, which can be installed next to the pumping stations.
This is achieved by various chemicals, such as calcium-nitrate or solutions of iron (III)-chloride.
For continuous level measurement of the chemicals they are using EasyTREK SPA integrated ultrasonic level transmitters, which can reliably measure the level of various chemicals and suitable for the existing FRT-4 surveillance monitoring system.
In 2014 a total of 10 systems including NIVELCO’s EasyTREK transmitters have been installed in the facilities of Sopron Waterworks, Budapest Sewage Works and the Heves Region Waterworks.
2014 - Military Base, Shorabak, Afghanistan :: Distributor: NIVELCO USA LLC.
The wastewater treatment plant located in Shorabak, Afghanistan is to be operated and maintained by Afghan National Army personnel, which means that the installed level measurement equipment has
to be easy to operate and durable in a difficult environment. The EasyTREK integrated ultrasonic level transmitter was selected due to the IP68 rated construction and long durability proven in many other field installations.
2014 - Department of Radiology, University of Pécs, Hungary
In the medical practice slightly radioactive materials are used in many diagnostic procedures. These materials are depleted after the tests from the studied subjects for example with the urine, which is then collected into containers. The radioactive wastewater can be let out into the canal system only after the expiry of the half-life. Until that point it is stored in a fully automated tanks system, where the level measurement is done by EasyTREK integrated ultrasonic level transmitters. The most important requirement is the security, this is why the integrated design has been chosen from the highly reliable and HART-capable (remote programmable) NIVELCO ultrasonic transmitter family.
2013 - Fenes Valley hydroelectric power station, Romania :: Distributor: NIVELCO Tehnica Masurarii
Flow metering solution for small hydroelectric power stations. The water which drives the turbines is measured by insertion type electromagnetic flowmeters. In order to provide be minimum required water amount in the stream an open channel flowmeter system with EasyTREK ultrasonic level transmitter, NIVOSONAR GPA Parshall flume and MultiCONT process controller is used. This system controls a dam gate (open-close) to provide the specified minimum yield. This water volume should provide proper living space for the water creatures in the river downstream under the dam.
2013 - Miskolc Water Works, Hungary
The sewage shafts at the Miskolc Water Works are equipped with crushers in order to pump protection. The crushers grind the bigger solid particles of the sewage and the incoming water reaches the pumps when it crossed the crusher. Originally the crushers were operating all the time, mostly unnecessarily. Now the grinder acts like a filter screen when not operating. When the contaminations start to build-up in front of the crusher the water level will increase inside the shaft. The water level is monitored by an EasyTREK ultrasonic level transmitter. The measured value is displayed on a UNICONT PMG unit and the crusher equipment is controlled by the UNICONT PMG. When the water level raises the crusher will start, grinds the driftwoods therefore the water level will decrease and then the controller stops the crusher. Thanks to this controlling solution the crusher is operating only if necessary resulting great energy savings.
2012 - Budapest Sewage Works, Hungary, Budapest
In 2012 the South-Pest wastewater treatment plant of Budapest Sewage Works established a new treatment technology called Organica Food-Chain Reactor. In this activated sludge water treatment process the water level control of the activated sludge basins has became necessary to be able to transfer the proper water amount to the biological stage. The water level is continuously measured by an EasyTREK SPA-360-4 type integrated ultrasonic level transmitter. The output signal of the instrument is transmitted to the PLC controlling the biological purification stage. The PLC controls the activated sludge basins floodgates on the basis of the measured level values.
Disinfection is a very important step in the food & beverage industry where the CIP process is used for this purpose. The CIP process uses concentrated (37%) hydrochloric acid, the acid storage tank is equipped with EasyTREK SPA integrated ultrasonic level transmitter. The instrument has excellent chemical resistance against aggressive media and it measures reliably through the acid vapour.
