Grundfos Direct Sensors™ 1
1. Vortex flow sensors
IntroductionThis data booklet comprises an overview of the
Grundfos vortex flow sensor range and related products.
Fig. 1 Grundfos vortex flow sensors
The trademark Grundfos Direct Sensors™ is owned and controlled by the Grundfos group.
The Grundfos vortex flow sensor is an integrated flow and temperature measurement system designed and validated for harsh aqueous environments. The flow measurement is based on the vortex principle. The system elements include a flow pipe with an integrated bluff body and a differential pressure detector.
Fig. 1 Bluff body inside a vortex flow sensor
When a bluff body is placed in a flow inside a pipe, a series of vortices will be generated periodically on each side of the bluff body. These vortices propagate down stream giving rise to periodic pressure variations, which can be detected by the differential pressure detector. The frequency of the pressure variations is proportional to the volume flow through the pipe.
Fig. 2 Operating principle
The bluff body is designed to optimise the pulse strength of the pressure variations at the position of the differential pressure detector. The bluff body is an integrated part of the injection moulded flow pipe, or supplied as a composite insert solution.
Flow ranges are determined by the pipe diameter and the signal processing parameters. The differential pressure detector key elements are a bulk micromachined silicon chip and a microprocessor-based signal-conditioning circuit, both on the same PCB. The conditioning circuit converts the pressure reading to a signal proportional to the flow through the pipe.
The electronics are protected by an IP44 composite housing.
The chip has a square membrane, which deflects due to pressure. Strain gauges are incorporated in a Wheatstone bridge configuration on stress intensive positions on the membrane. The pressure and temperature sensitive area (the membrane region) is coated on both sides by an extremely corrosion and diffusion resistive thin film (Silicoat®). The coating provides direct environmental robustness of the chip. The separation of the media and media-free zones is provided by O-ring sealing.

VFI general data
Vortex flow sensor, industry
Fig. 3 VFI sensor
Technical overview The VFI is the industrial version of the Grundfos vortex flowmeter range. The VFI is based on the principle of vortex shedding behind a bluff body. The VFI has no moving parts and is built into a stainless steel pipe. The rugged design allows the VFI to be used in a wide range of applications as a cost-effective and accurate flow sensor.The flow sensors are supplied with flanges or with threaded ends for use with union nuts.

VFS general data
Vortex flow sensor, standard
Fig. 33 VFS and VFS QT Sensors
Technical overview Grundfos Direct Sensors™, type VFS, is a series of combined flow- and temperature sensors (two-in-one) based on the principle of vortex shedding behind a bluff body. The VFS sensors are designed for high-volume production and are fully compatible with wet, aggressive media. The VFS sensor utilises MEMS sensing technology in combination with a novel packaging concept using corrosion-resistant coating on the MEMS sensor element. This makes the VFS sensor very robust and ideal for high-volume OEM applications.
Applications• Thermal management in solar heating systems
• industrial process flow control
• flow rate detection for pump controls
• monitoring of pumps, valves and filters
• temperature control
• domestic hot-water systems
• heat metering indication (solar heat pumps).
Features• Flow ranges: 1-12, 1-15, 1.3-20, 2-40, 5-100,
10-200 and 20-400 l/min.
• designed to operate in glycol mixture
• based on vortex shedding
• voltage output (ratiometric, ideal for use with microprocessor and PLC)
• compact and robust design
• approved for drinking water: WRAS, KTW, W270, ACS
• SiliCoat® technology.
Benefits• No moving parts
• flow- and temperature sensor in one package (two-in-one sensor)
• quick temperature response (direct media contact)
• compatible with wet, aggressive media
• cost-effective and robust construction.
