## What is SmartCylinder?

With the SmartCylinder app, and Siargo’s Smart Gas Cylinder Meters installed, you can access and control your gas cylinder anytime and anywhere for the ultimate management of the cylinder gas consumption, cylinder gas leakage, and cylinder manufacture and inventory.

Gas consumption

Siargo’s smart gas cylinder meters utilize the company’s MEMS mass flow sensing technology that enables the accurate measurement of the gas mass consumption and the meter also transmits the data via the BLE or GPRS to the Cloud database that the user can access anytime and anywhere. User can interact with the meter via the app for the initial gas volume register.

Gas leakage

The smart gas cylinder meters shall detect the possible gas leakage and alert the user via the app or registers in database.  User can setup the limit of the leakage to be alerted.
Instant flowrate
This function shall enable the user to monitor the instant flowrate to avoid over or under supply, for example. This can be critical for oxygen delivery.

Battery status and time usage

The app also provide the battery status that shall alert the user to timely change the battery in order not to run out of power in case this meter is solely powered by battery. Other functions include usage time which is required by some specific applications.
