Ultrasonic Flowmeters for Ultra High Purity Liquids, Z-Shaped Tube; 0 to 20 LPM, 1/2" OD Tube Connection

Improved bubble robustness due to DSP technology

No contamination due to noninvasive measurement

Choice of Z or U shaped flow patterns

Designed for flow measurement in high-purity processes in the pharmaceutical and semiconductor industry, flow is sensed by two piezoelectric transducers mounted at both ends of the measuring path of the fluid stream, generating and receiving an ultrasonic wave. The wave going in direction of the flow (with-stream wave) is accelerated and the wave going against (against-stream wave) the flow direction is slowed down. The two waves are processed by a signal converter. The difference of the transmit time of both waves is proportional to the velocity of the fluid.

The standard configuration of the LEVIFLOW? flowmeters consists of a flowtube with two sensor and a converter with digital signal processor (DSP) and 4-digit display. The single-channel flow converter is DIN-rail mountable and features an alarm abd totalization. Various signals (analog, digital input and digital output) are provided and can be configured with PC software. A two wire RS 485 bus allows arrays of multiple flowmeters.

What's Included:

Flowtube with two sensors and flow converter. Note: Extension cables are required and sold separately below.
