The battery-powered FLOMIC FLOMIC FL5044 ultrasonic water meter is intended for operational and invoicing measurements of instantaneous flow rate, pressure and consumption in water piping in observance of standard EN 14154 in water works, water distribution systems and other industrial applications. This water meter is of a compact design with the IP 68 protection class. It is characterised by high measurement accuracy and long-term stability over a wide range of measured values. The meter does not need any external power supply, does not include any moving parts and, has significantly lower hydraulic losses. The technical parameters and other features of the FLOMIC water meter make it suitable not only for water consumption measurements, but also for water-leak tracking and monitoring of the general condition of water-supply networks, where the meter output signals can be connected via data transfer systems to remote computer control stations. The measurement method utilised by this meter is a dual-beam transit-time pulse method based on evaluation of the time needed for an ultrasonic signal to cross the distance between two measuring transductors. In the standard version, the meter measures instantaneous flow rate (in m3/hour) and the total volume of water passed through the meter (in m3) in the given flow direction. The measured data are converted into passive pulse output signals.
