Flow Loggers monitor and log the flow rate as well as total flow. These can be used for liquid as well as airflow monitoring with appropriate sensors. Flow sensors can be pulse output type or 4-20mA or mV. Flow can be shown in various units like liter/minute or liter/hour or m3/hour. Flow loggers find applications in the process control industry, chemical plants, water supply schemes, and test-beds or automated test equipment.
Flow loggers come with a memory that can save data for long intervals or with SD cards as usually Flow Loggers are located at remote locations. They also come with a facility to send data remotely using GPRS technology or Wi-Fi. They come with AMR (Automated Meter Reader) equipment to assist in billing applications.
