Memosens technology is Revolutionizing Liquid Analysis

Sensing, Signal Transmission and Signal processing is the basic flow pattern for measuring Parameters. Sensor, Cable & Transmitters are the main assembly parts of this system.

Over the years, many revolutionary technologies has been adapted to get highly accurate & most precise measuring though still we have many challenges which distort the final measuring value.

When it comes to Liquid Analysis, which places massive demand on sensor and on the transmission of measured value from the sensor to transmitter. Moisture, Harsh environment like dirt, corrosion, salt bridge, over pressure and interference potentials are the challenges.

In addition, when it comes to pH measurement, low measuring signals and very high sensor internal resistances require a high-impedance connection to the transmitter. The measured value being altered or even caused the complete failure of the measurement with the presence of moisture in conventional, analog connector systems. Field calibration is the main challenge for the contact type sensors plus there is no process to diagnose disturbed signal transmission.

Memosens: Contactless, Digital, Innovative

What’s special about Memosens? The measuring signals are digitalized at sensor head and transferred inductively (contactless). As a result of contactless bi-directional signal transmission, the inductive coupling also provides the power supply to the sensor. 

Memosens: Simple, Waterproof, Cost-efficient

The Memosens plug & play system is 100% waterproof and resistant to dirt, corrosion, salt bridges, over pressure and interference potentials. The robust Memosens connection also means high resistance to mechanical influences. Even cable lengths of 100 m function perfectly for applications with Memosens technology.

Its inductive signal transmission results in perfect galvanic isolation. Precise measurements are possible even with difficult potentials. Further measures for equipotential bonding such as solution ground are unnecessary.

Memosens sensors are available for pH, ORP, conductivity and oxygen parameters.

On-site sensor exchange using pre-calibrated sensors reduces process downtime and regular regeneration extends sensor lifetime. Qualified personnel can pre-calibrate Memosens sensors in the laboratory that benefits users with increased quality of the calibration and measurement precision in turn. Memosens prevents expensive process downtime during sensor replacement due to very short maintenance times.

Memosens: Data Management, Predictive Maintenance

Predictive Maintenance – Reliable process management with intelligent diagnostics functions such as conditions of use, sensor wear, operating time and a CIP/SIP or autoclaving counter ensure greater safety, effectiveness and reliability. A load matrix evaluates the individual wear data of the sensors and the adaptive calibration timer calculates the optimal process-dependent maintenance cycle.

Memosens 2.0 stores 8 times more data, such as calibration histories and load matrices, paving the way for true predictive maintenance and enhanced IIoT services. It also offers full flexibility in hazardous areas since all Ex sensors can be matched to all Liquiline transmitters with the respective approval. Memosens 2.0 sensors are backwards-compatible for fast integration into existing systems.

Automation in Oil & Gas Sector

The Oil & Gas sector is one of the biggest industries in the world providing employment opportunities to thousands of workers worldwide. In India, it is among the 6 core industries and the most influential in the country’s economy. In fact, as stated by Mr Dharmendra Pradhan, Minister of State for Petroleum and Natural Gas, India’s oil demand is expected to grow at a CAGR of 3.6 per cent to 458 Million Tonnes of Oil Equivalent (MTOE) by 2040, while demand for energy will more than double by 2040 as economy will grow to more than five times its current size. An industry that is growing in such a rapid pace requires optimized operations of upstream and downstream stations that can help achieve monitored control, increasing efficiency and thereby more productivity and profitability. Hence, there is a strong need of sophisticated automation and instrumentation systems at all stages of Oil & Gas production process that is basically an extensive method of Exploration, Well Development, Production & Site Abandonment.

Drilling department in the sector is one such department that is and will reap the maximum benefits of advanced automation solutions. Automated drilling technology aids in making economically viable wells in lesser time, thereby increasing the number of production wells. As the crude oil is extracted and transferred to the production site which is usually a zone of harmful gases, proper measures need to be taken. Such petrochemical products are kept in highly compact atmosphere in analyser shelters so that no harmful gas can be penetrated outside. Hence, while increasing productivity and efficiency is one of the major goals in the industry, the major focus however is on safety. The safety of, but not limited to, environment owing to gas leakage. The successful outdoor installation and operation of analysers calls for protection from environmental hazards owing to extreme temperature. These installations need high maintenance by the workers and hence, consideration of the working conditions of such maintenance workers who must attend to these equipments on a daily basis is mandatory and is of utmost priority. It must be ensured that the workers have an access to a safe and comfortable working environment.

Not only that, another factor that needs careful consideration is that of provision of accurate and uninterrupted readouts of data measurements, an error in which may lead to explosions. This is done to achieve maximum production while not at the cost of safety operations.

To meet such industry challenges that are constantly evolving, Axis India offers resilient and hazard proof Analyser Shelter that ‘protects’ the instruments mounted in such crisis zones to prevent gas leakage. The shelters are carefully engineered and built in such a way that it can withstand temperature extremes and ensure ease of maintenance and accurate data reading. Bringing the sample gas post extraction for further process directly into the analyzer electronics closure is potentially hazardous. If there is a leak, it can cause explosions, also increasing the risk of human exposure. To prevent such occurrences, the shelter by Axis is constructed as a fully insulated sandwich construction with stainless steel (316) inner and outer sheeting, making it suitable for corrosive and cold ambient conditions. Complete Interlocking ribbed structure lends better technology with extra strength. The shelter is provided with a heating & ventilation system and can be fitted with a full HVAC system. The complete shelter is designed, fabricated and tested in-house as an integrated system. With this approach, site installation work is reduced to a minimum. AXIS also provides complete Integrated Analyzer Shelter Systems and all related services from initial engineering through manufacturing, testing and field start-up. Analyzers Systems are normally supplied and installed in the special Analyzer shelter including air-conditioning or HVAC, power distribution, lighting, termination and junction boxes, gas and flame detection, relevant piping and wiring. It is suitable for Area Classification for IEC ZONE 1, Group IIC or IEC Zone 1, IIA IIB.

The commitment towards lending Oil & Gas sector a smooth functioning and increased productivity is what drives Axis India to constantly innovate and update their technological solutions.  


DAM Water Level Monitoring System

Project Introduction:

The Water Level from different dams located in State are to be monitored at the Central location. As the Dams & Central Location were the data are to monitored are geometrically apart from each other, the only way to have communication between them is GSM/GPRS.

The data from the dam side (7 different RTU’s) are being transmitted to Central Server RTU via GSM/GPRS. These data are to be integrated in the IEC 60870-104 based Pre-Installed SCADA System. The Central Server is a Modbus RTU.

The data is converted from Modbus RTU to IEC 60870-104 as the Pre-Installed SCADA was supporting IEC-104 protocol.

System Requirements

  • Centralized and stable monitoring platform for the data from different location.
  • Protocol conversion among Modbus and TCP/IP IEC 104
  • Easy integration with other pre-installed communication system.
  • Integration the data to pre-installed SCADA System.

Our Solution

The Analog & Digital values are being received at the Centralized master station side via Modbus RTU. The Modbus output can not to directly given to the pre-installed IEC-104 Server SCADA, so the Modbus output need to be converted to IEC-60870-104.

Our Multifunction Controller placed in between Modbus RTU & SCADA, which converts the Modbus data to IEC- 60870-104 format. The data from all the Dams can be monitored at the Centralized Location on to the IEC-104 based SCADA.
