The CAF1105019 is an ultrasonic flowmeter designed to measure the velocity of liquids in pipelines. It is a contact type flowmeter, meaning that it must be mounted inside of the pipe close to the liquid where the velocity of its flow is to be measured. The CAF1105019 is a highly accurate instrument and is robust, reliable and easy to maintain with only minimal service requirements and minimal electronics.

The CAF1105019 is constructed of a piezoelectric transducer bonded to a specially designed and machined body for isolation and stability. The transducer is flush mounted to the face of the pipe, or it can be mounted using a threaded plant connection. The transducer is held in place by the mounting hardware and a special filter is used to keep out debris, sludge and other contaminants.

The CAF1105019 relies on the Doppler effect principle. The transducer is used to send an acoustic pulse into the process fluid, and as the fluid passes the transducer, the sound waves are scattered and refracted off particles and micro bubbles in the fluid. As the sound wave is refracted, a frequency shift or “Doppler” effect occurs, which is detected by the receiver in the transducer. The frequency shift is directly proportional to the velocity of the liquid. The processor then calculates the volume flow rate from the instantaneous measurements.

In addition to measuring the velocity of a liquid, the CAF1105019 can be used to detect the presence of high concentrations of small particles or bubbles in a fluid which is useful for monitoring for the presence of flow anomalies such as cavitation or air entrainment.

The CAF1105019 has a wide variety of applications. It can be used to measure the flow rate in process pipes, cooling water systems, fuel air mixtures, sewage, effluent, and other liquids. It is particularly well suited for measuring non-reactive liquids with low solids content. It can also be used to measure the flow rate of high temperature liquids, and as an alternative to insertion-type flowmeters in situations where the pipe is too small or inaccessible for insertion sensors. The non-intrusive nature of the CAF1105019 also eliminates the need for hot work permits and safety concerns associated with manipulating and installing gauges and sensors within a pipe.

The CAF1105019 is ideal for both new installations and as a retrofit replacement for traditional mechanical gauges. It is also easy to install and maintain, and its use of the Doppler Effect principle makes it highly accurate and reliable.
