Frequently Asked Questions

Yes. AirScale devices do not work without calibration.

Each axle group must be calibrated so the system can convert air pressure → axle weight for your specific truck or trailer and suspension weight

Calibration defines the pressure-to-weight curve for an axle group.

At minimum, calibration requires two known weights:

AirScales calculates the axle-specific relationship between pressure and weight using these points.

Accuracy improves with additional calibration points, especially when they span the full operating range.

Best results come from:

• One empty calibration
• One or more loaded calibrations near typical operating weight

More calibration points = tighter fit = more consistent results.

Recalibrate only when the pressure-to-load relationship changes:

• Suspension components are replaced or repaired
• Air system behavior changes (leaks, leveling valve replacement)
• Axle configuration is modified

Routine seasonal changes, tire pressure changes, or weather do not require recalibration.

AirScale is a wireless load monitoring system that estimates vehicle weight by reading air bag pressure from your truck or trailer's air suspension system. It provides real-time weight estimates directly to your mobile device via Bluetooth or WiFi.

Yes. A subscription is required to unlock all features of the mobile app including:

• Real-time weight monitoring
• Cloud data storage and sync
• Historical data and reports
• Custom alerts and notifications
• Multi-device support

Good news: New device purchases include 6 months free subscription for 1 user!

AirScales accuracy improves with proper calibration. The more calibration points you use across different load levels, the more accurate your weight estimates will be.

Key insight: Calibrating at different load levels (empty, half-full, fully loaded) is more important than environmental factors. Once properly calibrated, readings remain stable across normal operating conditions.

Important: AirScales provides weight estimates, not certified measurements. Always confirm legal compliance using certified scales where required.

Note: AirScales assumes the air suspension system is functioning normally (no leaks or mechanical faults).

It totally depends on my mood honestly. But yeah, I'll probably let you return it up to 30 days after I ship it to you. I'll let you cover the cost of shipping it back and forth though! At this stage, I dont have returns set up with Stripe Payment, so I dunno how this will all work.

Installation is straightforward:

1. Drop the air out of your air bags, ensure that the bags are fully deflated
2. Connect the device to your vehicle's 12V power supply using the supplied power wire ensuring to connect the blade 5amp fuse on the red wire near your battery
3. Cut the air supply line between the air bag(s) and the load level sensor with a sharp blade
4. Install the supplied push to connect 3/8" T-Fitting into the air line. Install the pressure sensor and torque to 7.5 - 8.0 ft-lb
5. Connect the three wires from the AirScale device to the pressure sensor in the T-fitting: 5V (yellow), GND (white), and 0.5V - 4.5V sensor line (blue or green)
6. Mount the device in a secure location
7. Download the mobile app and pair via Bluetooth or WiFi

No complex wiring or special tools required. Most installations take 30-60 minutes per vehicle.

Yes! If you're comfortable with basic mechanical work and have installed accessories on your truck before, you can install AirScales yourself. The installation guide includes step-by-step instructions with photos. Otherwise, any truck mechanic or shop can install it for you.

Perfect use case! Since each trailer has its own AirScale device, you can configure and monitor any truck / trailer configuration. The app automatically detects and connects to any nearby AirScale devices without any user interaction required to maintain connectivity.

Simple rule: One AirScale device per vehicle is recommended (truck or trailer). Each device can monitor up to three axle groups.

Common setups:

Each AirScale device can monitor up to 3 distinct pressure sensors simultaneously.

No. AirScales devices communicate wirelessly between themselves and only one is required to connect with your phone or with your truck wifi system. Usually the one mounted to your truck frame.

There are:

• No wires at the kingpin
• No connections between truck and trailer or trailer and trailer
• Each device is fully self-contained on its own vehicle

There are 7 indicator lights on the AirScales device in various places:

Normal operation: When connected to your truck or trailer, you should see 12V, 5V, MUX, 3.3V, and SYS lit.

Your calibration and settings are stored in the device's memory and won't be lost. When power is restored, the device will automatically reconnect to your phone.

This usually means the device isn't actively connected. Common causes:

• Device is powered off or lost 12V power
• Bluetooth is disabled on your phone
• Device is out of Bluetooth range (typically 30-50 feet)
• Another phone is connected to the device (only one connection at a time)

Check the device status indicator in the app - it should show "LIVE" with a green badge when actively connected.

One subscription covers one user account. Your account can manage multiple devices (all your trucks and trailers), but you can only be logged in on one phone at a time. If you have multiple drivers or phones, each needs their own subscription.

You can remove the AirScale devices and transfer it to your new truck/trailer. Just unbolt it and reinstall on the new vehicle. You'll need to recalibrate for the new vehicle, but all your subscription and account info stays the same.

Yes, AirScale devices are designed for harsh trucking environments and electrical connections are rated IP68 and IP69. Time will tell how good these electrical connections will be!

The only feature inside the app that requires an active subscription is to see the full actual weight of what you have loaded.

Device purchasers currently get 6 months free! After that, plans are only $5/month, or $50/year.

I'm not sure yet, that is the plan and will likely be implemented Q3 of 2026. Currently, AirScale devices require connectivity to a cellular phone with data.

• Works offline: Real-time weight readings, local data storage
• Requires internet: Cloud sync, historical data access from other devices, remote monitoring

Yes, if the AirScales device has power and an internet connection (via WiFi or your mobile phone connected via Bluetooth with cellular data), and the device can see data, you can monitor load updates remotely.

Load data updates every 30 seconds or so and is visible via the web app at beaker.ca/dashboard or through the mobile app. Great for fleet managers or checking weights while physically not near the vehicle.

No. The AirScales device does not track your location.

Your phone, however, can track your location and this data might be saved in the AirScale app, I honestly dont see a need to do so yet, but maybe one day I will. You can disable location services entirely in your phone settings - AirScale will work fine without it.
