Product Description

Product Overview

1. Product Overview:

TEC-lll is a gas volume corrector that enables PTZ, PT or T conversion. The device is designed to measure volume, energy and flow gas. Primarily battery powered, with the possibility to connect external power supply.

2. Approvals:
TEC-lll accords with standard EN 12405-1:2021 and EN 12405-2:2012.
ATEx accords with intrinsic safety explosion-proofstandard EN60079-0, EN60079-11 housing protection meets lP66 of standard EN60529.

3. Main Advantages:

• Industrial housing cooperates with various types of gas meter like turbine, rotary, ultrasonic by LF, HF, Namur, Reed contact, Encoder.
• Friendly user menu interface, equipped with 256 x 160 monochromatic dot matrix LCD display and 6-buttons touch screen.
• 4 independent serial transmission ports (2xRS485/R$232 + Optical interface 62056-21 + Bluetooth 5.0).
• Built-in GSM 2G/3G.4G, NB-loT modem (option).
• Various l/0 interfaces: up to 7 configurable inputs, Up to 4 binary or frequency outputs with photoelectric isolation.
• Low-power consumption design, built-in lithium battery to provide power for more than 6 years under the specified operating mode, up to three batteries.
• Large capacity and varities of metering data records and event archive function, Non-volatile in the lifetime (periodic record, daily record, monthly record, event archive, etc.).
• Multi-level security protection: independent hardware switch, seal sticker, lead seal, login password.
• With tamper-proof magneticinterference detection and opening cover detection alarm.
• Optional additional second external pressure transducers based on a built-in temperature sensor for comparison.
• Additional 4mA~20mA two-wire analogue current output, the parameters can be configured.
