TECHNICAL DESCRIPTION 1 General description ULTRAFLOW® 54 DN150-300 is a static flow sensor based on the ultrasonic measuring principle. It is primarily used as a volume flow sensor for thermal energy meters such as MULTICAL®. ULTRAFLOW® 54 DN150-300 has been designed for use in heating and cooling installations where water is the heat-bearing medium. ULTRAFLOW® 54 employs ultrasonic measuring techniques and microprocessor technology. All calculating and flow measuring circuits are collected on one single board, thus providing a compact and rational design and, in addition, exceptionally high...

TECHNICAL DESCRIPTION 6 Pressure loss Pressure loss in a flow sensor is stated as max. pressure loss at qp. According to EN 1434 max. pressure loss must not exceed 0.25 bar unless the energy meter includes a flow controller or functions as pressure reducing equipment. The pressure loss in a meter increases with the square of the flow and can be stated as: Q = kv  Dp where: Q = volume flow rate [m³/h] kv = volume flow rate at 1 bar pressure loss Dp = pressure loss [bar] FCCN FDCN FECN FECP FECR FFCP FFCR FGCR FGDS XXX - code for final assembly, approvals etc. - determined by Kamstrup.
