QCT_PA12 SERIES
The QCT_PA12 Series in-line ultrasonic flow meter has no moving parts, non-wetted sensor, and nothing in the flow stream to cause an increase in pressure drop; resulting in a very rugged, reliable and accurate flow meter. High accuracy and repeatability are achieved through the unique measurement section within the flow meter where the flow is conditioned and delta T is measured.
The small footprint, lightweight device is idea for low viscosity liquid applications including water-based products and oils. The all-plastic construction makes it the meter of choice for many corrosive fluids.

QLF SERIES
The QLF Series in line ultrasonic flow meter has been specifically designed for low flow rate applications that require excellent accuracy & reliability. The compact QLF Series has no moving parts, non-wetted sensors and no obstructions in the flow stream to cause an increase in pressure drop; this results in a very rugged, reliable and accurate flow meter. High accuracy & repeatability is achieved through the unique measurement section within the flow meter where the flow is conditioned and delta T is measured along the axis of the flow meter. The small footprint, lightweight device is ideal for low viscosity liquid applications including water, water-based products, oils, and its all plastic construction makes it the meter of choice for many corrosive fluids.
QUICK SPECS
- High accuracy
- 3500:1 turndown
- Minimum flow 0.001 gpm
- No moving parts
- Compact & lightweight design
- Low pressure drop
- All plastic construction
