The battery-powered ultrasonic FLOMIC FL5024, FL5025, FL5044 , FL5045 flow meters are 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. These flow meters are compact version with the IP 68 protection class. They are characterized by high measurement accuracy in or remote and long-term stability over a wide range of measured values. The meters do not need any external power supply, do not include any moving parts and, have significantly lower hydraulic losses. The technical parameters and other features of the FLOMIC water meters make them 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 utilized by these meters is a single-beam (FL5024, Fl5025, FL5045 ) or dual-beam (FL5044 ) 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 Gal/min) and the total volume of water passed through the meter (in Gal) in the given flow direction. The measured data are converted into passive pulse output signals.
