Frequently asked questions

What is the Modus Mini used for?

The Modus Mini is a single-channel electronic volume converter for commercial and industrial gas metering. It reads the LF pulse output of a gas meter up to 3 Hz, measures pressure and temperature, and converts the metered volume with AGA-8 DC92, S-GERG 88 or SGERG-mod-H2. Its flyer names medium and small industry, biomethane production and city gates as applications.

Should I choose the Modus Mini, the Modus or the Modus Slim2?

Choose the Modus when a station needs two PTZ channels and extra inputs, with Modbus or CTR protocol in ATEX Zone 0. The Modus Slim2 is a compact PTZ converter with integrated pressure and temperature sensors and a GSM/GPRS modem for Zone 0. The Modus Mini is single-channel with an NB-IoT / Cat-M1 modem, DLMS/COSEM protocol, a 15-year metrology battery and ATEX Zone 1 certification.

Do you supply the Modus Mini in Saudi Arabia and the GCC?

Yes. Pietro Fiorentini Saudi Industry in Al Khobar supplies and supports the Modus Mini for gas metering projects in Saudi Arabia, the UAE, Qatar, Kuwait, Bahrain and Oman. Send us your meter type, pressure range and communication requirements, and we will prepare a quotation.
