The flow meter is a compact instrument incorporating the latest electronics and digital signal processing technologies, realizing high performance and easy operation. With the use of high-speed micro-processor, the response time is as fast as 1s or less, housed in a IP-65 enclosure (NEMA-4x). The system is well suited to most environments. The welding-socket (stainless steel) incorporates a fully removable transducer with feed through assembly. Each feed through has an integral ball-type shut-off valve to allow removal of the transducer for repair, replacement or cleaning, without dewatering the pipe. Programming of the flow meter is simple and can be accomplished with FlowVision, a Microsoft Windows compatible configuration and signal analysis program. It provides access to an extensive range of diagnostic information. HydroVision manufactures several flowmeter consoles to meet the specific requirements of various applications.

The Q-Eye PSC series is an extremely versatile flow measurement system designed for continuous operation and suitable for open channels and partially filled pipes. It is designed to measure flow in a variety of flow applications and meets Environmental Agencies and BS3680 requirements for effluent discharge. Its versatility enables flow to be measured with flumes or weirs using the depth to flow principle, or in clear channels using the velocity area principle. Versatility is further enhanced by options of air or immersed sensors to accommodate aggressive liquids and foaming.

The KATflow range of non-invasive flowmeters utilizes ultrasonic technology for the accurate flow measurement of liquids in full pipes. The portable device has been designed to meet the needs of the Service/Maintenance and Commissioning Engineer wishing to check the flow rate of liquids at different locations in the plant. The set-up of the unit is simple and user friendly in order to obtain the required flow information in minutes. The measurement of flow is based on the principle that sound waves are influenced by a flowing medium. Measurements are made by penetrating the pipe with ultrasound and subsequently time differences, frequency variations and phase shifts of the ultrasonic signals are evaluated. The ultrasonic sensors are clamped onto the outside of the pipe, thus eliminating the need to dismantle the pipework and interrupt the process. The KATflow 230 can be applied to any type of standard pipe carrying clean or dirty liquids.

Mainstream uses the area-velocity method to give a continuous or time sampled measurement of liquid flow. Suitable for any liquid containing bubbles or suspended solids, even in minute quantities, the velocity detects reflected ultrasound. Signals from the probe are analysed using Phase Coherence Processing (patents pending). Phase Coherence Processing only accepts signals containing verified velocity information.

Mainstream uses the area-velocity method to give a continuous or time sampled measurement of fluid flow. Suitable for any liquid containing bubbles or suspended solids, even in minute quantities, the velocity probe detects reflected ultrasound. The percentage of signal accepted is the signal quality. A high signal quality confirms the integrity of the measurement. The verified velocity signals produce a histogram of the flow velocities. Analysing this histogram gives the mean flow velocity. The liquid level is measured by a submerged pressure transmitter or ultrasonic sensor. Flow cross-sectional area is deduced from the liquid level measurement and a stored description of the pipe or channel cross-section. The flow velocity is multiplied by the flow cross-sectional area to give the flow rate, and integrated to give the total discharge.
