Bubbler Module Teledyne Isco’s TIENetTM
330 Bubbler
Module technology is ideal in flow streams affected by harsh weather, debris, or corrosive chemicals. Since the depth of flow is determined by measuring the pressure needed to force
bubbles out of the line, you are able to calculate flow rate using one of the meter’s built-in flow conversions, or a user-defined level-to-flow relationship.

Continuous-wave Doppler Teledyne Isco’s TIENetTM
350 Area Velocity
Sensor continuously transmits an ultrasonic signal into the flow stream. The signals are reflected off bubbles and particles, and then return to the sensor with a frequency shift (Doppler effect) which is proportional to velocity. A differential pressure transducer in the sensor measures liquid depth in order to determine the wetted area. Flow rate is then calculated by multiplying the wetted area of the flow stream by its average velocity.

Non-contact Ultrasonic
If you are experiencing any of the following —
With the Teledyne Isco TIENetTM 310 Ultrasonic
Level Sensor mounted above the flow stream, transmitted sound pulses are reflected off the liquid surface. The elapsed time between transmitted and returned signals determines liquid level. Flow rate is then calculated using one of the meter’s built-in flow conversions, or a user- defined level-to-flow relationship.

Non-contact LaserFlow™ Velocity Sensor
191
Laser Doppler velocity sensor is a first in non- contacting flow measurement technology for open channels. Teledyne Isco’s LaserFlow Velocity Sensor utilises technology that sees below the surface. Velocity measurements are achieved by penetrating the surface for multipoint subsurface velocity readings. A non-contacting ultrasonic transmitter measures the liquid head height to determine the wetted area. Multiplying the wetted area by the average velocity yields the flow rate. Flow during surcharge conditions can be measured with an optional, integrally- mounted continuous-wave Doppler area velocity sensor.
