Set the sensor to work The assembly and set to work of the instrument are carried out by two simple steps that allow a quick and precise installation: 1. INSTALLATION OF THE SENSOR ON THE WET-TAP CLAMP SADDLE 2. VERTICAL POSITIONING OF THE SENSOR INTO THE PIPE Warning: the F6.61 allows installation into pressurised pipes without system shutdown;...

2. VERTICAL POSITIONING OF THE SENSOR INTO THE PIPE • Be sure the sensor is in the upper position. • Calculate the DISTANCE between the sliding bush C (Fig. 2) and the sensor body: DISTANCE “L” [mm] = (0.15 x Internal Diameter) +S (wall thickness) +K (distance between external pipe and end of the thread) - 15 •...
WIRING General recommendation Always ensure the power supply is switched off before working on the device. Make wiring connections according to wiring diagrams. • Terminals accept 26 to 12 AWG (0.08 to 2.5 mm2) • Strip around 10 mm (0.4”) of insulation from the wire tips and tin bare ends to avoid fraying.

EARTHING The magmeter normally is uninfluenced by low levels of electrical noise. In some applications it is necessary to connect the sensor to earth to eliminate electrical noise. The earthing can be done as following described: • connecting the Ground Wire (black wire from the sensor body) to an External Earthing passing through a cable gland.
CALIBRATION Manual Calibration Manual calibration can be done setting the micro switches on PCB in the proper combination in according with the pipe size (from d20-DN15 up to d>200-DN>180) where sensor will be installed. Positions are reported in the following table. Lock position is a No Functioning Combination while the USB combination is for accessing to the USB connection.
CALIBRATION BY USB The F6.61 hot tap magmeter can be connected to a PC and the operator can be connected to a PC and the operator can calibrate the instrument and set all parameters using dedicated software on USB pen drive (software can be dowloaded freely from FLS website) Procedure for setting - plug FLS Pen Drive into a USB port of PC...
OUTPUT MODE The F6.61 hot tap flow magmeter features 1 solid state relays and 1 analog output 4-20mA in addition to a Open Collector for frequency remoting (mainly for the interfacing of F6.61 with a FLS monitor) and a Open Collector for the flow direction remoting.

F6.61 K-FACTOR TABLE (ONLY FOR FREQUENCY OUTPUT) K-Factor is the number of pulses which a sensor produces for one liter of measured fluid. Here below all K-Factors for water at room temperature are listed. K-Factor values can depend on the installation conditions. K-Factor has to divide the frequency generated by F6.61 in order to achieve the flow rate (l/s).
Correction formula for K-Factor calculation according to real internal diameter: K-Factor_NEW = (K-Factor x ID²) / ID_NEW² ID = Value in the table for the internal diameter (in mm) ID_NEW = New value for the real internal diameter (always in mm) K-Factor = Value in the table K-Factor_NEW = New K-Factor value for the specified internal diameter Example:...
