Page 4: Intended Use
The GF U1000 V2 ultrasonic flowmeter is used to obtain an optimal measurement of the volume flow and flow rate in steel and plastic pipes with outside diameter from 22 mm (0.86”) to 180 mm (7”). Measurable pipe sizes are dependent on pipe material and inner pipe diameter. -

Page 6: Design And Function
Electronics module Pipe The GF U1000 V2 consists of an electronics module (3) and a guide rail (4), which together form a single unit which is fixed to the pipe (6) by pipe clamps (2). The GF U1000 V2 is supplied with power through an external 12 – 24 V power adapter (1). -
Page 7: User Interface
Instruction Manual In addition to the flow rate, the GF U1000 V2 HM models measure the temperature difference between the flow and return of the system via two Pt100 temperature sensors. The difference in temperature between the flow and the return, in combination with the volume of water that has passed through the system, is used to calculate the energy difference in the medium. -
Page 8: Scope Of Delivery
Installation Identify suitable location for flow measurement The GF U1000 V2 requires an even and uniform flow profile, since distortions in the flow can cause unpredictable measurement errors. In many applications, however, it is not possible to have a uniform flow rate through 360°. This may be, for example, because there are air bubbles inside the top of the pipe, or turbulence in the pipe, or sludge at the bottom of the pipe. -
Page 9: Identify Suitable Location For Temperature Measurement (Hm Versions Only)
Instruction Manual NOTICE Incorrect Measurements Measurements can be distorted if the transducers are positioned close to upstream pipe components and fittings such as pipe bends, T-branches, valves, pumps and similar obstacles. To ensure the GF1000 V2 is positioned at a place that has an undistorted flow profile, the transducers must be mounted sufficiently far from possible sources of distortion to prevent these from having any effect on the measurement. -

Page 12: Selecting The Pipe Adapter
Instruction Manual ► Define optimal sensor distance with entering your pipe credentials in the GF U1000 V2 start-up wizard (see section 8.4 Start-Up). (E.g. B-4 for PVC-U pipe with 50 mm inside diameter) ► Loosen the sensor mounting screws, sufficiently to loosen the flow sensors and allow sideways movement. -

Page 16: Electrical Connection & Outputs
Electrical Connection and Outputs NOTICE The U1000GF U1000 V2 operates in the voltage range 12 – 24 V (AC/DC). The power supply must have a minimum rating of 7 VA per instrument. To fully meet the requirements of EMC regulations, a 12 V connection is recommended for domestic and light industrial applications. -
Page 17: Pulse Output
The Alarm functions allow you to set the alarm switch to Normally Open or Normally Closed. 8.2.1 Volumetric pulses The GF U1000 V2 default pulse width is set to 50ms which represents half of one pulse cycle. A 50ms pulse width is required for most mechanical counters. -
Page 18: Frequency Mode
Instruction Manual Formula to obtain Volume per Pulse based on a (default) 50ms pulse width: Volume per Pulse >= maximum flow rate (in litres per minute) / 600 Example for maximum flow rate of 500 l/min: Volume per Pulse >= 500 l/min / 600 = 0.833 litres per pulse Rounding up to nearest whole litre: Set Volume per Pulse to 1 litre. -
