Polysonics SX40
The Polysonics SX40 is a dedicated Doppler flowmeter which utilizes a patented digital signal processing technique to determine the flow of liquids that contain particulate or air bubbles. The meter incorporates clamp-on sensors which are easily installed for sludge management in sewage treatment plants and industrial applications such as slurry and effulent monitoring.
The Hydra SX40 is designed as a permanently installed flowmeter. Its large backlit graphics display provides excellent visibility even in poorly lit environments. As well as flow rate and flow total, a flow trend is available to quickly analyze flow over a period of time. This is especially useful for analyzing pump cycling activity. Standard outputs include 4-20mA, RS232 serial interface and up to four programmable relays. The flowmeter also incorporates a 90,000-point data logger.
