Deskripsi Electric Volume Converter Vemmtec PTZ Box 3.0

Advantages
The PTZ-BOX 3.0 is an electronic converter for gas volume meters (for custody transfer) with extended features: 
* LF or HF single/dual pulse input or encoder
* Sensors included, pressure sensor internally or externally mounted 
* Additional pressure or temperature sensor optionally available 
* 4 user configurable Quick Access Buttons for direct access to important values and sub menus 
* Tariff counters (max. 4) 
* Energy counter 
* Password structure with different access levels 
* Digital/pulse/analogue outputs (4)
* 10 point flow meter curve correction 
* Several compressibility calculation methods, including the full composition AGA 8 calculation
* Configuration and communication software for Windows™ included

Operation
The PTZ-BOX 3.0 is a battery powered or optionally line powered volume converter for gas measurement applications. Applications are with gas flow meters providing LF/HF pulse or encoder signals.
The converter is equipped with energy-saving pressure and temperature sensors. Standard cable length is 2.5 meter; the maximum cable length of an external pressure sensor is 5 meter and for the temperature sensor that is 10 meter.
PTZ-BOX 3.0 calculates the compressibility factor Z of the gas as well as the conversion factor C with the measured absolute pressure and temperature. From these values, it calculates the volume at base conditions and the base flow rate. All calculations are performed according to EN 12405, AGA 7 and ISO 6976.

The compressibility factors Z and Zb may be fixed or calculated for natural gas according to: 
* AGA NX 19 (mod.)
* AGA 8 G1 or G2
* AGA 8-92 DC (full composition)
* SGERG 88
