Everyday we come across a news of hazardous incident of fire in plant, hotel, resident, industries, etc, the tragedy happen due to the leakage of combustible/explosive gases or sudden electrical spark and the carelessness of the management and security systems.
we all know that in market there is lots of gas leak detection and early fire detection system and gas leak detection systems which stop the horrible incident by intimating the managements by actuating Alarm, locking gas Supply System or can say close the solenoid valve , messages & many more options are there .
But sadly saying that in India 60%people who needs fire and gas leakage monitoring and control system in their premises are not using these system in their premises .
We request you to put your concern towards the security system, Life and Environmental issues and stop these kind of painful incident in our country.
For all types of gas detector process instruments energy saving & field instruments you can contact us
We feel pleased if we can assist you, guide you and provide you our best consultancy and product services.
We at Alvi Automation promise you to provide you best German Technology to save your Life, Money, Plant, Industries, Building etc. ..

The detector is explosion proof IECEX, ATEX certified with SIL 2 safety level and suitable for installation in hazardous area Zone 1 and Zone 2.
The instrument can be installed at landfill application, sewage treatment plants, fertilizer industry, gas bank etc.
It is available with LCD Display, onboard relay contacts, flashing alarm LEDs, auto diagnostic watchdog, non-intrusive calibration, with the industry standard linear analog output.
online, continuous monitoring of methane / natural gas / PNG / LNG leakage or LEL level, wall or duct mount, with / without display & relays, ATEX certified with safety integrity level SIL 2, explosion proof for Zone 1, 2
Methane gas sensor – online LEL monitor for natural gas, LNG, PNG for Zone 1, 2 with ATEX, IECEX, SIL 2
Methane, chemically known as CH4 is highly flammable, lightweight gas with LEL at STP 5% v/v.
Methane gas detector series is highly robust, industrial grade, flameproof or explosion proof gas detector for methane leakage detection or LEL monitoring. Methane is also available in form as natural gas, pressurised natural gas (PNG), liquiefied natural gas (LNG).
The detector is used for online, continuous monitoring of the flammable concentration of methane in PPM, %LEL or %Vol terms in ambient air or in duct or pipeline. It is ATEX, IECEX certified with SIL 2 safety integrity level for hazardous area installation Zone 1 and 2.
The sensor transmitter offers linear, proportional analog output in industry standard current signals, over measuring range of 0-1000, 0-2000 PPM, 0 ~ 100 % LEL (lower explosive limit). The detector works on highly sensitive catalytic bead-based pellistor sensor cell, with low response time. It has unique feature of auto diagnostic watch dog with zero point tracking feature. Due to its 12-bit microprocessor based control unit, it offer high accuracy over long term. The detector is also equipped with sintered filter with flashback arrestor for enhanced safety.
It also offers optional features like inbuilt LCD display, flashing alarm LEDs, onboard potential free relay contacts (24VDC @ 1 A), RS485 serial interface with Modbus RTU communication.
