Calculate the total number of gallons and acre-inches applied during a 12-hour set time. All water meters are looks similar even in functionality, in this video I explained this by showing Kranti water meter as an example. You need to supply the recommended VCC Voltage to the Sensor (3.3 or 5V depends on sensor). Applying this amount during a 72-hr period requires a flow rate of 160 72 = 2.22 acre-in per hour. In a flow metering device based on the Bernoulli Equation the downstream pressure after an obstruction will be lower than the upstream pressure before. The constant value of water density is 997 kg/m, gravitational constant is 9.81 m s -2. Click the Calculate Flow button to see your flow rate at the observed conditions.
