    The LB4-A single-phase watt-hour meter is the latest development in the induction type meters. The meter has been designed in a modular construction allowing for fewer components with the benefits of reduced cost and increased reliability. Servicing costs have been kept to a minimum due to the construction design, and the wide measuring range ensures accurate measurement at both low and high loads.
   The LB4-A meter enables electricity supply authorities to install the meter with total confidence a long and trouble-free service life is guaranteed by a state of art design concept.
Excellent performance in high peak loads, while at the same time accurately recording low consumption at off-peak periods are standard task for our meters.


The specialized finishing of components, and high stability of the brake magnets, the non-lubricating register mechanism, the robust measuring assembly and the high strength at continuous and surge over voltage stresses are the outstanding characteristics ou or meter.
   The LB4-S meter has been designed and manufactured in compliance with IEC521 and BS5685.
