Magnetic Flowmeter Battery powered  Comaccal F45 flow meter was developed for placing in spaces without supply voltages and it is ideal to be fitted in main pipelines, drainage or various sewage conduits. The flow meter is excellent in high accuracy within full-scale flow rate. Before every measurement, automated diagnosis of all functions and parts necessary for correct measurement is carried out. Based on the results, the flow meter is able to identity empty pipes and invalidate the entire measurement, or conversely, the meter can evaluate the flow direction and include the results in relevant summary registers. The battery life  is directly dependent on the selected measurement period, for example  a period of 10 seconds the life will be  5 years.
