IMPLEMENTATION OF SMS-BASED WIRELESS TECHNOLOGY FOR ULTRASONIC VELOCITY MEASUREMENT IN LIQUIDS

In the present work, a virtual instrumentation setup utilizing GSM service for remote access via short message service (SMS) for measurements of ultrasonic velocity in liquid and liquid mixture is designed. Communication to the designed instrumentation system is achieved between a mobile phone (server) attached to it and another mobile phone (client). The instrumentation system can be controlled and monitored from anywhere covered by the GSM service by exchanging SMS between server and client under the software control designed in VB6.0. Ultrasonic velocities at various temperatures are measured through SMS between the server and the client mobile phones.
