Okapi Solar Calculator|工具線上App不用買

Use the light meter, on your phone or tablet, to measure sunlight strength in watts/m²

Track and share sun position (azimuth and elevation) anywhere in the world, on any date

Solar air heater calculator helps determine output in BTU or watts from a solar heater

Wirelessly connect to Okapi Solar Air Heater control systems for real time data viewing, data logging and much more!

Try before you buy! After downloading the app, if you feel that you don't need it, just click "Refund" in the App Store (within 2 hours of purchase) for a full refund.

Solar and HVAC calculator:

Enter measured temperatures from Inlet and Outlet (°F or °C)

Enter measured wind speed from the outlet (FPM or m/s)

Enter dimensions of the outlet (inches or cm), diameter or rectangular

Select if equivalent diameter calculation (Huebscher) is required for rectangular outlets

Enter elevation or have the App calculate it automatically using GPS and an internet connection

App calculates:

Temperature rise between inlet and outlet

Output from the system in watts or BTU

The area of the Outlet

The airflow (CFM or m³/min)

The F value (specific heat of airflow mass), which is based on the elevation

Unit conversions are also available: convert between °F and °C, between cm and inches (including squares and cubes), convert between watts and BTU.

Share button to allow sharing to social media, email etc.

Sun position activity

Choose a location using GPS or the built-in Google map

Automatically determines the Timezone (internet connection required)

Or enter the timezone manually

Choose a date if you want a forecast or historical data

The app displays sunrise time, solar noon time and sunset time

The app displays the current azimuth and elevation of the sun

Use a slider to slide all the way from sunrise to sunset and watch the solar azimuth and elevation change as you alter time

Built-in compass (requires specific sensors and works best outside)

Shows you the pitch of the Android device. Great for measuring sloping angles!

All above output data can easily be shared via email, social media etc.

Specify level of detail in shared data via options

Estimate Sun strength (like a Radiometer or Pyrheliometer)

Uses light sensor on Android device to measure sun strength (insolation) in watts/m² or BTUh/ft²

Toggle button to convert between watts/m² and BTUh/ft²

Share button available to send your data via email, social media, Bluetooth, Google cloud print, Google+, Facebook, etc

Okapi wireless system required for following features

Okapi real time data monitoring!

Connects Android device via Bluetooth to Okapi Solar Air heater control systems

Displays output for each connected heater: Inlet and Outlet temperatures in °C or °F, Temperature rise between inlet and outlet, fan speeds and thermal power output (kWh or BTUh)

While connected to Okapi system, app logs Okapi performance

Share Okapi real time data to email or social media such as Facebook

Data logging:

The app can be left running, while connected to an Okapi, system to log data

Database stores accurate hourly heating calculations

User ability to enter report queries and share reports for graphing or further analysis

Settings (for entry of detailed data regarding connected Okapi systems)

Detect elevation at the location of the solar heaters (GPS and internet required)

Calculates the F value (heat capacity of airflow mass) based on elevation

Set whether share data should be in detailed or basic form

Privacy option: Set whether or not you want to include your GPS location in share data

For each heater:

Name the heater

Set whether the outlet is round or rectangular

Enter the diameter, or width and height, of the outlet

Set whether equivalent diameter is required.

Enter the measured wind speed when the fan is running at 100% (FPM or m/s)

Enter the area of the collector's active surface area

Outlet area is then calculated for you, as is the Maximum airflow (in CFM or m³/min)

Convert between metric and imperial units
