ADS Model 4000 & 5000 Area-Velocity Flow Meter - Doppler Velocity Sensor,  A/V

Description

This sale is for one ADS Acoustic Doppler Velocity Sensor, compatible with ADS Model 1500, Model 4000 and Model 5000 and 5000AG Flowshark flow meters. This sensor has approximate 50 foot cable. I have 10 of these that were operational when removed from service but not recently tested. It will be up to you to test the sensor when you receive it and if it is not working you can return it for exchange within 30 days. I also have ADS Ultrasonic depth and pressure depth sensors, see my other advertisements. These sensors are no longer available from the manufacturer.  Extend the life of your investment by purchasing some spare sensors now.
The Doppler Velocity sensor mounts at the bottom of the pipe. It emits a wide, omni-directional sound wave at a specific frequency upward into the flow.  The sound wave bounces off particles in the flow and returns to the sensor. The velocity sensor measures the change in the sound wave's frequency from transmission to reception.  This change is used to determine the velocity of the flow based on the Doppler effect.  The Doppler effect describes the shift in frequency of a sound wave emitted by a moving object in relation to a stationary point.  In this case, the moving objects are particles in the flow, the stationary point is the velocity sensor, and the received signal is the reflection of the sound wave (emitted by the velocity sensor) off the particles.
