Heat meter - ultrasonic flow meter Ultraheat 2WR7

Ultrasonic flow meter ULTRAHEAT 2WR7 is designed to measure flow in the water heat exchange systems using ultrasound.
Scope
Ultrasonic flow meter ULTRAHEAT 2WR7 is intended for use in as flow sensor for calculators when taking into account the consumption of heat or cold. Readings of the flowmeter may need to play through the optical port. Not suitable for systems with water-picoline mixtures.
Composition
Ultrasonic flow meter ULTRAHEAT 2WR7 consists of a flow sensor (full metal version) and attached to the electronic module. These two components are rigidly interconnected by a cable. Meter flow is also available in protection IP 65 (standard: IP 54).
