11 Mechanical registration Mechanical registers have traditionally been used in a variety of mobile and fixed-site applications. Mechanical registers are ideal for applications without electrical power and can be installed on virtually all LC meters. Mechanical counter with ticket printer—Large-numeral counter provides 5-digit resettable and 8-digit non-resettable totalizers. Printer generates an imprinted record of the transaction which is legal for use in resale applications. Mechanical preset counter—Available for either single-stage or two-stage valve closure. Sets a predetermined volume and controls a mechanically linked valve. Optional microswitches convert mechanical motion to an electronic signal for control of remotely located valve, pump, and alarms. Counter-mounted pulser—Supplies an electrical signal to remote totalizers, batch controllers, rate-of-flow recorders, etc. Pulser models include dry reed (1 or 10 pulses per revolution), solid state single channel (100 pulses per channel) or solid state quadrature (50 pulses per channel). Mechanical rate-of-flow indicator—Direct-reading dial providing instantaneous response and dependable accuracy to within 1% of flow rate through meter. Cast aluminum case with ball bearings throughout. Readouts available in gallons, liters, and dekaliters per minute. Mechanical temperature volume compensator—Uses a fluid-filled capillary system to sense product temperature and automatically correct counter reading for product volume changes due to temperature. When the temperature is 60º F, a 1:1 output ratio is supplied to the register. Output ratio is adjusted upward or downward depending on temperature fluctuation around 60º F. Pulse output device—Weights and Measures approved, provides a high resolution, unscaled pulse stream. The meter rotor is magnetically coupled to an optical encoder that has a signal which is directly proportional to the liquid flow through the meter. No dynamic seals to fail or leak. Easily adapts to most remote totalizers, batch controllers, computers, and other scalable pulse receiving devices.
