Users can view the instantaneous flow rate, total flow, total usage duration, and battery level. Based on proprietary MEMS sensing and IoT technologies, Siargo’s smart flow meters provide a comprehensive solution for the intelligent management of gas cylinder filling, storage, and transport, as well as gas and microfluidic flow measurement and process control. The devices measure instantaneous flow rate, total flow, and usage duration for gases and microfluids, while also monitoring remaining cylinder capacity. Data may be transmitted wirelessly over Bluetooth to mobile devices. Siargo's smart meters can either be powered with batteries or a power cable, offering flexible installation options. Users can configure the meters on-site with the tactile buttons, set password protection for data security, and set alarms for high/low flow rates and low remaining cylinder capacity.

About

Authenticator

Read full description

This is not a basic two-factor authentication app. It is a full personal security platform — codes, passwords, an encrypted vault, a private browser and autofill — built for people who take account security seriously enough to want everything in one place and nothing left unprotected. Use two-factor authentication on your accounts but manage your codes, passwords and sensitive files across three or four different apps and want everything consolidated under a single layer of encryption and Face ID. Have lost access to accounts before because you changed phones and had no encrypted backup of your 2FA codes — and want Cloud Sync that keeps everything recoverable without compromising what is stored. Type passwords and copy 2FA codes manually every time you log in because your authenticator and your password manager do not talk to each other — and want Auto Fill that handles both in one step WHAT YOU GET INSIDE 2FA Authentication — secure TOTP and HOTP code generation for any account that supports two-factor authentication, codes refreshed every 30 seconds QR Scanner — instant account setup by pointing the camera at any 2FA QR code MFA and OTP Support — full multi-factor and one-time password compatibility across all standard authentication formats Backup Codes — stored recovery codes for every account so a fallback always exists when the primary device is unavailable Password Manager — encrypted credential storage for every login, organized and accessible without switching apps Secure Vault — end-to-end encrypted storage for sensitive files, recovery keys, private notes and anything that does not belong in a standard notes app Private Browser — built-in browser for sessions that should stay separate from your regular browsing history, with vault access directly inside it Auto Fill — automatic code and password entry across apps and websites so nothing needs to be copied or typed manually Cloud Sync — encrypted backup across all your devices so your full setup is recoverable on any new device from the moment you sign in Widgets — home screen and lock screen access to your most-used codes without opening the app Encryption — end-to-end protection applied across every feature, every stored item and every synced file SUBSCRIPTION & ACCESS Important: Subscription required; no free content.

Verdict

The call
