QC-DT-1
Hybrid Ultrasonic Flowmeter
Installation:
Fluid Requirements
The QC-DT-1 Hybrid Ultrasonic Flow Meters can measure fluid flow in virtually any fluid in which sound waves can travel. The QC-DT-1 meters are
considered “hybrid” because they can measure fluid flow using either the Doppler or Transit Time methods. The QC-DT-1 ultrasonic sound transducers are
clamped to the outside of the pipe wall and include no moving parts. This method of flow measurement is safe, non-intrusive and very easy to service.
The Doppler measurement method requires particles be present in the flow stream to “reflect” the sound waves. The meter may be operated in the
Doppler mode when the fluid contains 0.02% to 15% (200 to 150,000 ppm) of particles .
The Transit Time measuring method requires relatively “clean” fluid to enable the sound waves to complete their circuit. The meter may be operated in
the Transit-Time mode when the fluid contains 0% to 10% (0 to 100,000 ppm) of particles. To allow for changes in the fluid’s particle count, the S2 monitors
the signal gain and employs an Automatic Gain Control (AGC) algorithm that periodically adjusts the gain maintain the optimum power level.
The speed at which sound travels in the fluid must be known. The factory will configure the meter for a known fluid during the initial configuration. The
QC-DT-1 includes a 5-button user interface and remote PC software that can be used to configure the meter. Many common fluids are listed in the software
and can be selected directly from the menu. Provided the speed of sound in the fluid is known, custom “unknown” fluids can be input manually by the user.
A list of various fluids and their sound speeds are provided in the user manual.
Flow Stream Requirements
The QC-DT-1 sound wave beam is only affected by fluid that actually passes through the beam and therefore, the meter will not measure accurately if
the fluid velocity is not consistent across the entire pipe diameter. Flow disturbances such as pumps, elbows, tees, and valves in the flow stream can cause
swirl patterns and vortices that will affect the measurement. Install the transducers on a straight run of pipe as far as possible from any disturbances. The
distance required for accuracy will depend on the type of disturbance.
Minimum Straight Pipe Length Requirements
The meter’s accuracy is affected by disturbances such as pumps, elbows, tees, valves, etc., in the flow stream. Install the meter in a straight run of
pipe as far as possible from any disturbances. The distance required for accuracy will depend on the type of disturbance.

The meter can be mounted on horizontal or vertical runs of pipe.
Mounting on the sides (3 o'clock and 9 o’clock) position on horizontal pipe is recommended.
Mounting anywhere around the diameter of vertical pipe is acceptable, however, the pipe must be completely full of fluid at all times.
Back pressure is required on downward flows to ensure a full pipe.
See the minimum straight length of pipe requirement chart above.
The meter can accurately measure flow from either direction.
