Metering Solutions
From thermal energy metering to flow and water measurement, Renteknik helps select and configure the right metering solution for your application, operating conditions and integration requirements.
01
Kamstrup Thermal Energy Metering
Accurate heating and cooling energy measurement with flexible communications. A complete thermal energy (BTU) metering system combines a calculator, a flow sensor and matched supply and return temperature sensors. Renteknik selects the components and configurations for your application, from individual buildings to central plants and district energy systems.
Ideal for: Commercial buildings, district energy, tenant metering, central plants, and heating and cooling systems.
02
Electromagnetic Flow Measurement
Renteknik works with reputable suppliers and maintains inventory of electromagnetic flowmeters for suitable glycol and mixed-fluid thermal metering applications. These are paired with compatible calculators and temperature sensors. Our team checks the complete configuration to ensure suitability for the fluid and operating conditions.
03
Clamp-On Flow Measurement
Renteknik can offer clamp-on flow measurement solutions for suitable liquid applications. Sensors fitted to the outside of the pipe measure flow without cutting into the pipe, helping reduce installation work.
04
Mechanical Water Metering
Mechanical water metering can provide a lower-cost option for suitable applications. Contact our team to discuss the options for your project.
Built for Connected Buildings
