The Series 380 BTU meter is an all-in-one energy usage package for monitoring hydronic heating or cooling systems. This meter accurately measures flow and temperature differential to compute energy and can interface with many existing control systems.
The rugged design incorporates an impeller flow sensor and two temperature probes. One temperature probe is conveniently mounted directly in the flow sensor tee. The second is placed on either the supply or the return line, depending on the application. These minimal connections help simplify installation and save time.
Kamstrup ultrasonic heat meters are produced to MID Approval EN1434 – a stringent European standard that ensures that the accuracy and quality remain constant, so you can be confident that every meter is as good as the last. The ULTRAFLOW® flow sensors use microprocessor technology and ultrasonic measuring techniques.
Efficient metering and design
The flow is measured using bi-directional ultrasound based on the transit time method, with proven long-term stability and accuracy. All circuits for calculating and measuring are collected on a single board, providing a compact and rational design in addition to an exceptionally high level of measuring accuracy and reliability.
Danfoss Sono® compact energy meters offers both primary side and secondary side meters for heating as well as cooling applications. They can be used in single-family houses, apartment buildings and commercial buildings.
All meters are high quality, ultrasonic meters for the highest accuracy and longest lifetime values.
FLEXIM’s non-invasive permanent or portable Thermal Energy meters allow for an easy determination of the thermal energy flows within a building.
In times of rising energy prices and environmental regulations, the optimization of thermal energy flows is the most crucial issue. From heat delivery between central heating plants to real estate end users or heat transfer flows in industrial processes: controlling and balancing the flow of energy is of utmost importance for cost-conscious users.
With temperature measurements at the inlet and at the outlet of a system as well as accurate flow measurement at the outlet, the FLUXUS Thermal Energy meter calculates the thermal energy flows from outside the pipe wall, being virtually maintenance-free.
The values can easily be transmitted to a PC for display and analysis. The data obtained can be used for energy flow balancing or it can be transmitted to a process control system.
