ABSTRACT: The Water Meter (should we come up with a product name?) is a water quality meter designed by the Humboldt State University Engineering 215 - Intro to Design class, and implemented on the WetLand mobile habitat.


Water Meter

Project Background: WetLand is a mobile self-sustainable island-based ecosystem started in summer of 2014 on a barge located on the Delaware River in Philadelphia, PA. The goal of WetLand is to offer a workspace for artists; a stage for forums on our shared future; and to combine art, life on the water, architecture, and environmental technologies.

OBJECTIVE: The water meter is designed to monitor the volume, flow, and quality of water which is collected and stored on the WetLand habitat. Water on the WetLands habitat is collected through desalination of water from the Delaware river and through rainwater catchment. This water is filtered for use onboard, but requires monitoring to insure its quality for use.


Design

The water meter, designed by Team X, tests the water quality for the WetLands project. The design is composed of five sensors that read the volume, pH, salt water content via conductivity, temperature (Fahrenheit), and the flow of the water into the water tank of the drinking water on the barge. All of the values the sensors take are read by an Arduino programmable microchip and displayed on a liquid crystal display (LCD) screen. While displaying these values it will be saving those values to an SD card that is incorporated into the Arduino microchip.

volume Sensor

The volume sensor is an ultrasonic ping sensor. The sensor emits ultrasonic sound waves that bounces of the water in the tank and reflects back to the sensor. From the time it takes to be emitted and the time it takes to return to the sensor depends on how far away the water is from the sensor. using a conversion factor that varies depending on the distance the volume is calculated and displayed to the LCD screen.

pH Sensor

The pH sensor is an Atlas pH sensor that tests for acidity or basicity of the water in the tank. This sensor MUST be constantly stored in water or else it will break and need to be replaced. Also this sensor needs to be calibrated approximately once a week because it is constantly being stored in the testing solution and will need to be cleaned; however, if it is not being constantly used it can be stored and may last up to a year with out being calibrated.

Saline Sensor

The saline sensor is derived from a small volume/conductivity sensor. The probe will read a conductivity value and through a conversion find the parts per million of the salt concentration on the barge.

Flow Meter

The flow meter is to be stored at the inlet of the water take so the amount of water the barge is taking on is known.

Temperature

the temperature sensor is used to display the temperature of the water when it is being stored.


LCD Screen

The LCD screen is where all of the data that is read and calculated by the Arduino is displayed. This is designed to be easy to read and comprehend. the reader should right away know if that water they have is potable or if it needs to further be purified.
