Measuring technology manufacturer Krohne’s ultrasonic flowmeter Optisonic 3400 is now available with heat meter approval according to MID 2014/32/EU Annex VI MI-004 (and harmonised CEN EN1434, OIML R75) in accuracy classes 1, 2, and 3.

Target applications include district heating networks, commercial and industrial heat metering applications, as well as energy and utility applications in combined heat and electricity generation.

Optisonic 3400 is the only inline heat meter that provides high accuracy measurement of heated water with three ultrasonic paths throughout the whole diameter range DN25…2000 / 1…80".

To ensure stated accuracy classes, each heat meter undergoes a three-point factory calibration performed with water.

With its direct path configuration, Optisonic 3400 is not susceptible to magnetite scaling like meters that use reflectors.

It offers bi-directional flow measurement and a fully welded construction without potential leak points.

Optisonic 3400 also features enhanced diagnostic and status indications (according to NAMUR NE 107) and measurement of the velocity of sound to gain additional information about medium and process.
