Flownetix 107v3 - 7mm bore ultrasonic flowmeterThe third iteration of the 100series now available with a 7mm bore for push fit connectors, ideal for drinks dispense applications 
Applications
The Flownetix 100series uses innovative ultrasonic technology to provide a non-invasive flow meter at low cost. The meters have no moving parts so it cannot clog or jam due to contaminants in the flow. In addition, the unit features automatic temperature and viscosity compensation and low pressure drop.
The Flownetix 107v3 is designed particularly for use in drinks dispense applications where the use of 3/8" pipework is common and can be connected using standard John Guest® 3/8" Speedfit® fittings. The meter is easily cleaned using pellets or chemicals.
Flownetix 100v3 products are available with two electronics options. The "A" versions incorporate a simple NPN pulse output with 1000 pulses per litre by default and is the lowest cost. The "B" version adds a voltage and current output as well as a pull-up type pulse output. Both versions incorporate the same serial interface as used on the award winning Flownetix 300series® range of consumer water meters which can be used by OEM, volume and distribution customers to configure output scaling and other features allowing for larger and more flexible stock holding.
Measurement principle
The instrument utilizes an ultrasonic transit time in-line flow cell:
Sound transmitted upstream is accelerated by the flow, sound transmitted downstream is decelerated. The resulting time difference is proportional to flow and converted by a microcontroller into an output signal.
The 100series® products are low cost alternatives to mechanical meters and suitable for use in many applications where reliability or performance improvements over mechanical solutions are required. High volume production techniques enable the Flownetix® 100series® to be manufactured for the largest demands. OEMs and high volume users can customize output types, plastic materials and cases to their own application.
