E N V O LGas Volume Converter

SIS intoduces his new generation

of T, PT or PTZ gas volume converter ENVOL.

Compliant with MID directive, ENVOL was

developed in close cooperation with the admin-

istrators of gas networks to offer innovative

functionalities in the gas volume conversion,

thus minimizing to strict minimum the installa-

tion and start-up phase.

Its communication capabilities combined

with large data logger functionalities make

the ENVOL device a high performance gas

volume converter.

TechnicalENVOL

Funct ional i t iesENVOL

ENVOL is a category 1 T, PT or PTZ gas volume converter in compliance with MID directive. ENVOL is a new generation of gasflow converter that integrates the latest electronic technologies(USB, Flash memory, microprocessor with low power consump-tion,...). Furthermore ENVOL offers advanced Datalogger function-alities and several communication ports (USB and RS232/485)allowing it to be used in any gas billing chain.

ENVOL allows conversion for combustible gasses 1st and 2nd family (according to EN437) and Nitrogen.

ENVOL is approved ATEX to be used in hazardous area (zone 0).

40 days• Daily volumes and indexes registered for

100 days• Monthly volumes and indexes registered

for 14 months• Thresholds on volume overrun

Measurements • Current pressure, temperature and flow values• Daily average pressure and temperature

registered for 80 days

Output • Digital outputs :• Unconverted volume pulse retrans-

management

Conversion alarm • A conversion stop alarm is generatedwhen the converter is overunning thework limits (P, T or calculation method).The following informations are regis-tered :• Conversion stop duration• Hourly converted volume during

alarm• Daily converted volume during alarm• Unconverted index during alarm

• Parametrable standby values are thenused for conversion

Event log • 400 last events recorded (including alarms)

Modbus link • Slave mode• PSTN, GSM/GPRS modem• PLC or RTU linkAdresses table (contact us)

• Master mode• chromatograph with gas parameters

reading for conversion / calculation

Integration example

• DisplayENVOL has a graphic display and a two multi-function button keypad. This display allows not only the exploitation of the recordeddatas but also the configuration of the main parameters.

• SoftwareENVOL can be configured and operated via a laptop with the SESAME software, locally or remotely thanks to its intuitive anduser-friendly interface. (Refer to SESAME software brochure).
