Multical 403 Ultrasonic Energy Meter

Quick Overview

The Multical 403 is designed to monitor the energy transfers in all types of thermal installation where water is used as the energy-conveying medium. The meter utilises an ultrasonic flow meter and two temperature sensors to measure the flow rate and temperature of the outgoing and returning water to calculate the energy transferred. Suitable for pipe diameters from ½" to 2" with threaded connections and flanged connections of DN25 to DN50. The meter also includes an in-built data logger that can provide yearly, monthly, daily, hourly and minutely values. Meter are also MID Class E1 approved and suitable for billing purposes for use in housing associations, blocks of flats and small industry applications.
