The ultrasonic flow meter is a liquid flow measurement device that emits ultrasonic signals into the flow path to measure flow of
any liquid. Ultrasound techniques have several advantages over the conventional methods, such as orifice plate, venture and
turbine meters, Transit-times at no-flow condition are utilized to eliminate the time delays in the non- liquid parts of the meter
from the measured transit-times. The transit times and the transit time difference at no-flow conditions are calculated for the
necessary environmental conditions, and stored in the flow computer. There are several flow meters available in the markets of
warranty being extended from 1-2 years here we are dealing with extending battery life up to 6 years and make cost effective and
efficient flow meter. A system is implemented with GSM module through advance technology. The ASIC GP-21 is specially
designed to capture the pulses (sinusoidal tone burst). The associated electronic unit provide for processing of the sensor signals
and visualization of the values of instantaneous flow rate and total fluid volume passed through the meter and fluid sensor and
fluid pressure with for archiving of the measured data in specified time intervals in the internal meter memory unit.
