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.

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.

• Catalogue

• Literature

• Service

• Sizing

• Replacement

• CAD drawings.

Catalogue

This section is based on fields of application and pump types, and contains

• technical data• curves (QH, Eta, P1, P2, etc.) which can be adapted to the

density and viscosity of the pumped liquid and show the number of pumps in operation

• product photos• dimensional drawings• wiring diagrams• quotation texts, etc.

Literature

In this section you can access all the latest documents of a given pump, such as

• data booklets• installation and operating instructions• service documentation, such as Service kit catalogue and

Service kit instructions• quick guides• product brochures.

Service

Fig. 85 WinCAPS CD-ROM

WinCAPS is a Windows-based Computer Aided Product Selection program containing detailed information on more than 185,000 Grundfos products in more than 20 languages.

The program contains the same features and functions as WebCAPS, but is an ideal solution if no Internet connection is available.

WinCAPS is available on CD-ROM and updated once a year.

Sizing

This section is based on different fields of application and installation examples, and gives easy step-by-step instructions in

how to• select the most suitable and efficient pump for your installation• carry out advanced calculations based on energy

consumption, payback periods, load profiles, life cycle costs, etc.

• analyse your selected pump via the built-in life cycle cost tool• determine the flow velocity in wastewater applications, etc.

Replacement

In this section you find a guide to selecting and comparing replacement data of an installed pump in order to replace the

pump with a more efficient Grundfos pump. The section contains replacement data of a wide range of pumps

produced by other manufacturers than Grundfos.

Based on an easy step-by-step guide, you can compare Grundfos pumps with the one you have installed on your site.

When you have specified the installed pump, the guide will suggest a number of Grundfos pumps which can improve both

comfort and efficiency.

CAD drawings

In this section it is possible to download 2-dimensional (2D) and 3-dimensional (3D) CAD drawings of most Grundfos pumps.

These formats are available in WebCAPS:

2-dimensional drawings:• .dxf, wireframe drawings• .dwg, wireframe drawings.

3-dimensional drawings:• .dwg, wireframe drawings (without surfaces)• .stp, solid drawings (with surfaces)• .eprt, E-drawings.
