MULTICAL® 601 and ULTRAFLOW® 54 are used for measurement of heating in all water based plants with flow temperatures from 2°C to 130°C and with ULTRAFLOW® 54 between qp 1.5 m³/h and qp 40 m³/h. The meter is simple to install, read and test.
MULTICAL® 601 and ULTRAFLOW® 54 contributes to keeping the annual operating costs at a minimum with its unique combination of high measuring accuracy and long lifetime.
MULTICAL® 601 receives volume pulses from the connected ULTRAFLOW® 54 and calculates the energy for every predetermined water volume. The energy calculation includes temperature measurements in flow and return as well as correction for density and heat content according to EN 1434.
MULTICAL® 601 and ULTRAFLOW® 54 can be supplied by either 24 VAC or battery.
MULTICAL® 601 can be supplied with two internal modules – a top module with clock backup, pulse outputs or M-Bus and a base module with M-Bus,or LonWorks. Furthermore, the base module includes two additional pulse inputs for connection of water and electricity meters, making it possible to collect all consumption data with one single automatic data reading.
ULTRAFLOW® 54 is a static flow sensor based on the ultrasonic measuring principle for use in heating installations where water is used as the energy conveying medium.
The flow is measured using bidirectional ultrasonic technique based on the transit time method,with proven long-term stability and accuracy. Two ultrasonic transducers are used to send the sound signal both against and with the flow direction.
The ultrasonic signal travelling with the flow direction reaches the opposite transducer first. The time difference between the two signals can be converted into a flow velocity and thus a volume.
ULTRAFLOW® is available up to qp 1,000 m³/h.FEATURES
