The Pipeline Model PSA-AV sensor is a fully integrated velocity and depth sensor with innovative sensor level signal processing for improved accuracy and stability.
The sensor utilizes continuous wave Doppler velocity technology proven in open channel flow metering for over 25 years. The sensor’s Progressive Spectral Analyzer (PSA – Patent Pending) technology improves quality of signal and accuracy of the readings all while reducing power consumption,
The pressure level sensor is 100% piesoresitive,ceramic pressure sensor being used for the first time in sewer flow metering. This feature offers improvements over the previously used technologies through a reinforced structure and provides more durability in the hostile and corrosive sewer environment. The ceramic sensor ensures high linearity across the entire range of measurement and reduces the effect of hysteresis (sensor drift). The sensor-to-water interface is a Teflon protected membrane that doesn’t puncture or foul from debris in the water.
Signal Processing in the Sensor
The sensor is uniquely designed to process the primary sensor signals virtually from within the signal source. This means all signal processing power is applied to producing the best measurement possible and not for separating “good” signal from noise introduced by a sensor cable. The sensor delivers processed measurements to the logger over industry standard RS-485 serial communication using Modbus Communication Protocol.
Fit for Duty
The sensor cable is the smallest diameter cable available in the market today. The smaller cable minimizes the potential for obstructioin of flow and a thinner cable is easier to manage during installation and maintenance.
Flow Meter Optional
This sensor is capable of being connected directly into many recording telemetry units including the FloWav ShortBoard Models 1000 and 2000 and other SCADA systems.
