“’LO”’ is an insert specially designed for use in pipes, sewers and/or full/partially full pipes.
It is equipped with four pairs of “V”-mounted insertion ultrasonic transducers.
The “LO” insert is combined with a transit time flow meter model MPCFNLO that uses the ultrasonic transit time method to determine the average flow velocity in its measuring section.
To then calculate the flow rate, this signal processing electronics needs to know the degree of filling of the pipeline, and this information is provided to it by a 4 ÷ 20mA analogue signal input from a dedicated, external level gauge.
The MPCFNLO can maintain accuracy even with very low water levels, and is also able to measure even when the pipe is full. As this newly developed electronics also has very sophisticated diagnostic functions to improve its performance.
