Temperature-Volume Corrector TC210
1 Brief description
1.1 Functions and performance features
General remarks:
The TC210 Temperature-Volume Corrector is used for the conversion of the gas volume
measured in the operating state by a gas meter to the standard state.
To determine the measurement conditions, the momentary value of the temperature is
measured. The pressure and gas law deviation factor (K-value) are entered as constants.
Power supply:
• Battery operation with a service life of up to eight years.
• Battery replacement possible without loss of data and without violation of calibration seals.
• Data retention without battery supply due to internal EEPROM.
Operator interface:
• 12-character LCD display, description of values with short designations.
• Operation via a key; special functions by pressing the key for at least two seconds.
• Restricted programming via keypad possible.
• Display values can be freely assigned by user.
• Calibration switch (separately sealed on the device).
• Two user locks (supplier's and customer's locks) with numerical codes.
• Access rights for each individual value can be set separately via interface (with appropriate
rights).
Pulse / signal inputs:
• 2 intrinsically safe pulse inputs for reed contacts or transistor switches, programmable as
pulse or signal inputs.
• Maximum counting frequency 2 Hz.
• Pulse value decade can be set for each input.
• Various counters for Vb and V (main counter, disturbance quantities, totaliser, adjustable
counter).
• Inputs can be sealed together with one covering cap for security under calibration regula-
tions.
Pulse / signal outputs:
• Two transistor outputs, each freely programmable as alarm/warning output.
• Pulse duration adjustable on pitch of 125 ms (max. output frequency: 4 Hz).
• Each output can be separately sealed and secured under official calibration.
