Accurate measurement and control of energy consumption are becoming increasingly important due to rising energy costs. Our advanced technology makes heat measurement effortless and highly accurate.
A modern heat meter offers more than standard consumption recording: it guarantees reliability and precision, and is equipped with advanced, future-oriented technology. ista's smart heat meters – such as the sensonic® 3 – feature modern electronics. In addition, the ultego®3 is equipped with ultrasonic measuring principles, which is why these meters are trusted by property managers and consultants worldwide.
Whether for new construction projects or replacements within statutory calibration periods, ista's high-quality, German-designed meters are a sustainable choice. Installation is flexible (horizontal or vertical), accuracy is high, and radio technology allows measurement data to be read remotely, easily and reliably. This ensures correct and transparent consumption recording and billing for all users.
The sensonic® 3 and sensonic® 3 calculator use advanced electronic measurement technologies that deliver accurate and up-to-date measurements. This ensures transparent and comprehensible heat cost calculation. The sensonic® 3 stands out thanks to its ease of installation, versatile application options, reliable measurement results, compact design and advanced technology.
Thanks to its compact dimensions and flexible mounting on all ista EAS connection pieces, installation is easy in almost all circumstances. The long battery life of 10 years and the robust design make the sensonic® 3 reliable and durable in use.
The compact version with integrated return temperature sensor is ideal for replacing existing meters. Thanks to the istameter principle and the proven 2-inch KOAX system, the replacement process is quick and easy.
The integrated wireless interface of the sensonic® 3 ensures accurate calculation of heating costs and makes collecting consumption data faster and more efficient than ever before.
Accurate recording of the smallest consumption values thanks to short response times of eight seconds and physical measurements.
Approved throughout Europe in accordance with the Measuring Instruments Directive 2014/32/EU and DIN EN 1434-6 for thermal energy meters.
Comply with all EED requirements for metering and distribution technology
Automatic meter reading on the due date and timely invoicing
Monthly checks of heat meters possible via remote reading
Transparency in energy consumption
Innovative, highly integrated microchip technology (ASIC)
Easy interchangeability thanks to the istameter® principle and simple integration into existing smart building systems
ista offers options for virtually every application – from compact meters for heating and cooling in homes to combined meters for large apartment complexes and commercial buildings.
No measuring system is complete without the right calculation system! Whether for small or large volume flows, our calculation systems are designed to collect, analyse, present and send data to our central database, which we can easily read.
The battery-powered sensonic 3 calculator is part of a heat meter that complies with EN1434. The sensonic 3 receives signals from the flow sensor and temperature sensors, guaranteeing accurate energy measurement.
The Sensonic 3 calculator can be combined with various flow sensors and temperature sensors in lengths of 3 and 10 metres and is available with pulse values of 1/25/250 litres per pulse.
With its high measurement accuracy, maintenance-free operation and long service life, the ultego® III smart helps to minimise annual operating costs. ultego® III smart is a static meter, fully electronic and has no moving parts. The meter is characterised by great flexibility and is easy to install. It can be installed either horizontally or vertically, straight pipe sections are not required and the meter is insensitive to pressure surges and overloads.
The ultego 3 smart consists of an ultrasonic flow sensor, two permanently attached temperature sensors and a calculation unit that determines energy consumption based on volume and temperature difference. Thanks to its integrated and interoperable wireless interface, the ultego® III smart can be seamlessly integrated into ista's radio system, enabling fully automated and digital collection of consumption data.
Areas of application
With a flow rate range of 0.6 - 2.5 m³/h, the ultego®3 smart is ideal for a variety of applications, including heating systems that use water as a heat transfer medium, transfer stations and larger heating systems in apartment buildings.
