Introduction
Device description
Gas volume conversion device PTZ-BOX 5.0 is a device used for measurements of gas volume at base
conditions and energy. It is designed to be used at gas measuring stations and pressure reduction-
measuring stations. It can cooperate with rotor and turbine gas meters.
PTZ-BOX 5.0 according to standard EN 12405-1:2018 is a gas volume conversion device
type 1.
Basic configuration of PTZ-BOX 5.0 offers:
- analogue input (pressure P1 – metrological channel),
- analogue input (temperature T – metrological channel),
- 5 configurable potential-free contact inputs (DI1 to DI5):
o
Measuring inputs LF1, LF2 (inputs DI3, DI4) – frequency up to 60 Hz with the
possibility of cooperation with Wiegand transmitters, detection of flow direction
(when using two LF inputs with phase shifted pulses)
o
TS input – default tamper switch, normally shorted (input DI5),
o
Up to 5 digital inputs (inputs DI1, DI2, DI3, DI4, DI5)

,
- 2 configurable NAMUR inputs (inputs DI6, DI7):
o
2 HF pulse inputs, frequency 0÷5000 Hz, detection of flow direction (when using two
HF inputs with phase shifted pulses)
o
HF2 (DI7) input can work with NAMUR encoder,
o
Up to 2 NAMUR digital inputs

,
- SCR input for SCR encoder (optionally, interchangeable with DI8 - potential-free digital input,
depends on hardware configuration),
- 4 outputs of „open collector” type:
o
DO1: configurable – binary or frequency (1÷1000 Hz),
o
DO2..DO4: binary,
- communications:
o
COM1 – standard RS-485, active with external power supply,
o
COM2 – standard RS-485, galvanic insulated, typically active with external power
supply, active on battery power when the casing is opened,
o
COM3 – optical interface, standard IEC 62056-21,
o
GSM 2G/3G modem (optional),
o
NFC – radio interface,
- input of external power supply,
- additional absolute pressure or overpressure p2 sensor (optional).

– Number of digital inputs depends on the configuration of the counting inputs.
The device can be configured using the supplied PTZcom software for PC. This software also allows
the readout, display and archive of both the immediate measured values as well as the contents of
the internal device archives.
