Grundfos VFD Digital Temperature Sensor

The digital VFD Grundfos Direct Sensors™ measure the temperature and the flow rate with a single measuring element, and then transmit the measured values directly via the RESOL VBus® protocol. Grundfos Direct Sensors™ can be used in aggressive fluids as well as in domestic water and thus are ideal for measuring the flow rate and the heat quantity in solar thermal and heating systems.

The VFD 2 - 40 l fast is ideal for DHW exchange modules due to its quick response time.

Features and Attributes:

• One sensor, two measured quantities
• Quick response time and refresh rate
• Includes fitting, insert and connection cable
• Quick and precise measurement through direct fluid contact
• No moving parts – no mechanical wear
