Smith Meter Large Numeral Counters (LNC) are mechanical registers for Smith PD meters with large, easy-to-read reset numerals: five digits on the 600 Series or six digits on the High Capacity 900 Series, with fine graduations on the right-hand wheel for one more digit of resolution. An eight-digit non-reset totalizer is standard. LNC accessories include low-resolution (1 or 10 pulses) and high-resolution (50 or 100 pulses) transmitters per right-hand wheel revolution, and a swivel adapter for rotating the register.
