New Ultrasonic Flow Meters

The battery-powered ultrasonic flow meters FLOMIC FL 5034 and FL 5054 from Elis (Czech Republic) are intended for measurements of instantaneous flow rate, pressure and consumption in water piping in
observance of standard EN 14154 in water works and water distribution systems. Flow meters are of a compact design with the IP 68 protection
class. They are characterised by high measurement accuracy and long-term stability over a wide range of measured values.
The meters do not need any external power supply, the live time of Li-battery is up to eight years and sampling of measurement of flow is
1s only. They do not include any moving parts and, have significantly lower hydraulic losses.
The technical parameters and other features of the FLOMIC flow meters make them suitable for water consumption measurements, also for finding of leakages of water in water-supply networks, where the meter output signals can be connected via data transfer systems to remote computer control stations. Internal datalogger makes possible the storage dates with chosen period and download them to a Notebook too.
The measurement method utilised by these meters is a single-beam (FL 5034) or dual-beam (FL 5054) 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 and the total volume of water
passed through the meter in the given flow direction.
