Ultrasonic Water Meter Flow Ranges Explained: Q1, Q2, Q3, Q4, and R Ratio

The correct choice depends on the vapor space and the process, not only the tank height Ultrasonic and non-contact radar instruments both measure the distance from a sensor to a product surface and convert that distance into level. Their physical signals are different, however. Ultrasonic instruments use mechanical sound waves travelling through the gas space, while rada...

Installation affects metering performance An ultrasonic water meter measures the transit-time difference between signals travelling with and against the water flow. The electronic calculation may be accurate, but the measurement still depends on the hydraulic condition inside the meter body. Air, an incompletely filled pipe, severe flow disturbance, a misaligned gasket, ...

Troubleshoot from the symptom, not from an assumption An ultrasonic level fault may come from the sensor, the installation, the process surface, the configuration, the power supply, or the control-system mapping. Replacing the instrument before separating these possibilities often reproduces the same fault with a new unit. Begin by recording the displayed level, raw dist...
