Page 3: Introduction
INTRODUCTION This volume flow meter is a robust industrial-grade inline gear flow meter that is available in an aluminium, brass or stainless steel design for the purpose of monitoring many different fluids. Available in seven connection sizes from 1/4... 3 inches for flow ranges from (0.02...0.20 gal/min) 0.1...0.75 l/min to (20...300 gal/min) 100...1100 l/min. -
Page 4: Unpacking And Checking The Product
UNPACKING AND CHECKING THE PRODUCT Perform the following steps once you receive the product: If the product packaging is damaged, ask the shipping agent to be present when the product is unpacked. If the product is damaged and the shipping agent is not present, ask for an inspection by the representative of the shipping agent within 48 hours of delivery and lodge a complaint with the shipping agent. -
Page 5: Functional Principle
FUNCTIONAL PRINCIPLE The volume flow meter is a float-type measuring device. A sharp-edged baffle (1) located in the piston assembly (2) forms an annular opening with the contoured measuring cone (3). The piston assembly features a cylindrical PPS/ceramic magnet (4) that is coupled magnetically to an external display magnet (5) which moves in direct response to the movement of the piston. -

INSTALLATION Important information CAUTION! This product should be installed and maintained by technically qualified personnel who have been trained on this specific product. CAUTION! Read through the instructions before you install the device. If you have any questions about installation or maintenance, call your local supplier to obtain further information. - Page 7 The volume flow meter is a device that is easy to install. However, the following measures are recommended to ensure it can be operated safely and without any faults: Align the pipeline precisely. The piping should be aligned precisely and be of the ...

Page 8: Installing The Volume Flow Meter
Unidirectional devices (such as this volume flow meter) must not be operated in the direction opposite to the one shown by the flow arrow. The piston acts like a non- return valve and blocks the flow in the opposite direction. This causes an excessive difference in pressure that may damage the internal components. - Page 9 2. Choose an installation location that is suitable for inspection and product maintenance. To connect the volume flow meter to the pipeline system, place a flat spanner on the wrench flats of the volume flow meter next to the pipe connection that is to be installed. Do not screw on the opposite end of the volume flow meter as this may cause leaks.

Page 10: Installing The Power Meter
Installing the power meter 1. Mount the power meter so that the fluid flows in the direction of the flow arrow. ( See Figure 1. Page 7 2. Install the power meter at any point in the hydraulic circuit, so that the volume flow, pressure and temperature displays can be read easily. - Page 11 Figure 5: Power meter in the transport case 4. Turn the premounted volume flow meter by hand after installation so that you can see the flow scale. Turn the volume flow meter by hand so Never use a flat spanner to turn the that you can see the display scale.

Page 19: Reconnecting The Magnetic Coupling
Reconnecting the magnetic coupling This piston-type volume flow meter is less sensitive to impacts and vibrations than other float- type designs. The magnetic coupling dispenses with the need for a mechanical connection, which may become worn or loose over the lifespan of the measuring device. However, a pressure spike or sudden increase in volume flow may cause the piston magnet to (see move at such a high velocity that the piston magnet (4) and the external display ring (5) - Page 20 The burst pressure protection breaks at a pressure of over 400 bar. Stainless steel volume flow meters are designed for an operating pressure of up to 350 bar and a safety factor of 3:1.
