3 Installation and mode of operation
3.1 Notes on installation
Information !
All instruments are carefully checked for functional capability before
shipment. Upon receipt of the device please carry out a visual inspection
of the outer packing for damage or improper handling.
Please contact the delivery carrier if you discover any defects. In such
cases a description of the defect, the type and the serial number of the
device are needed.
Information !
Unpack the equipment with care to prevent damage.
Information !
All instruments are carefully checked for order conformity.
Please check the delivery for completeness using the packing list. Please
examine the flowmeter nameplate to verify that the device was built
according to your order. Particularly check devices with electrical
components for the correct supply voltage.
3.2 Installation
Below the essential points concerning installation are described and have to be observed:
● Remove the transport securing device from the fitting.
● Prior to the installation verify that the float slides smoothly in the fitting without canting or
deadlocking. The pointer must follow the float movement smoothly.
● Verify that all accessories such as spring stop, gas/fluid damping are still correctly fixed in the
fitting.
● In the zero position (no flow) the pointer must be at the marked reference point (first line on
the scale). When moving the float manually to the end position, the pointer must be above the
final value of the scale.
● The flowmeter must be installed vertically – flow direction from bottom to top. For installation
recommendations refer to guideline VDI/VDE 3513 Part 3.
● The installation in the piping must be tension-free – therefore the piping must be positioned
parallel and aligned with each other.
● Avoid a corrosive atmosphere –provide ventilation where necessary.
● Ensure a sufficient distance of at least 200 mm to magnet-influencing parts such as solenoid
valves or ferromagnetic components e.g. steel brackets.
● Observe a lateral distance of at least 300 mm between two devices mounted next to one
another. The distance can be reduced by mounting the devices staggered by the length of one
device. To eliminate doubt the influence can be tested by moving the instrument up and down
