SAFETY INSTRUCTIONS 1 SAFETY INSTRUCTIONS 1.1 Intended use The orifice plate flowmeter Turbo-Lux® 3 is used to measure the volume of water in closed conduits. It is suitable for any point of installation, mounting position and flow direction (in compliance of the directional arrow). The necessary approvals of the FM Approvals, LPCB and VdS Schadenverhütung GmbH are available. Warning! The operator of these measuring devices is solely responsible for the suitability, intended use and corrosion resistance of the selected materials. It must be particularly ensured that the materials selected...

INSTALLATION AND MODE OF OPERATION 3 INSTALLATION AND MODE OF OPERATION 3.1 Installation notes Information! All instruments are carefully checked for proper function before shipment. Check immediately on receipt, the outer packing carefully for damage or signs of improper handling. Report damage to the carrier and your locale sale staff. In such cases, a description of the defect, the type and the serial number of the device is indicated. Unpack the unit carefully to avoid damage. Check the completeness of the delivery against the packing list. Check the name plate, if the delivered flow...

INSTALLATION AND MODE OF OPERATION » An inlet path of 5 x D requires a mounted quarter pipe before. Fig. 4 Inlet path and outflow zone at 5 x D with an one quarter pipe When using valves, fittings, ... before the orifice plate, an inlet path of min. 10 x D is always required. The outflow zone has to be min. 2 x D (fig. 5). » An inlet path of min. 10 x D is required if a valve, fitting or T-piece pipe is mounted before, where at least 5 x D must be available as a straight inlet section directly in front of the orifice plate (fig. 5). Fig. 5 Inlet path and outflow zone © MECON GmbH BA /...

INSTALLATION AND MODE OF OPERATION The installation can be in any line routing - horizontal to vertical - place (fig. 6). However, it is important to ensure that the flow direction of the arrow marked on the device and corresponds to the differential pressure sampling tube (fig. 9/10, pos. 7) is in the horizontal position. For attachment of the bypass meter, sufficient clearance must be provided. Important for the compliance of the measuring tolerance is the central mounting of the pipeline. The center offset must not exceed 0.5 mm. Mounting the bypass meter The bypass meter is only...

4 START-UP Read the exact value when a consistent flow has been attained and the float has reached a stable position. The pipeline must always be filled. Read the value at the greatest diameter (upper edge) of the float: Reference point For the bypass meter it is important that when starting up the pump, the shut-off-/control valve of the bypass orifice is opened min. 30 % to avoid hydraulic shocks or pressure surges that could damage the bypass meter. Fig. 8 Rotation bypass meter When the bypass meter is commissioned or set into operation, bubbles of air will initially accumulate at the...

Read the exact value On the scale the flow is printed in lpm (liters per minute respectively dm³/min.), USgpm (U.S. gallons per minute) and as percentage (100 % = rated power of the pump) for each nominal size and range. The following table provides more information about the scale display. Nominal Size Pump rating (USgpm) Flow range (USgpm) Step (USgpm) Graduation Flow range (Ipm) After device usage After measurements have been taken it is recommended that the measuring tube is either drained by inverting it or removed from the flow meter body. If removed the measurement tube must be...
