Focus Flow & level Powerful and portable ultrasonic flow meter Visual flow indicator
Sierra Instruments has intro- duced the next generation Innova-Sonic 210i universal transit-time meter for liquid flow measurement applications.
Featuring a high-powered ultrasonic pulse with improved digital signal processing, the unit is able to use just one set of trans- ducers over a wide range of pipe sizes. The 210i includes a tactile pushbutton interface with a large digital display that significantly simplifies set-up and data collec- tion. It comes with a fully field- configurable 4-20mA current loop analog output, 2GB SD memory card for data logging, and a suite of powerful yet user friendly programming menus that simplify data analysis. Complex totalisation functions are standard including parallel operation of positive, negative
and net flow totalisers. Offering an accuracy of +/-1.0% of read- ing, a wide operating tempera- ture range -40°F to 176°F (40°C to 80°C) and a bi-directional flow range of 0 to 40f/s liquids (0 to 12m/s), the flow meter can be used for a wide range of pipe sizes from 1.0” to 48” (25mm to1200mm).
The built-in totalisers record
daily, monthly and yearly totalised flow. Totalised flow for the past 64 days and months and even over the past five years may be viewed.

Valves with integrated positioners for precise control
Burkert globe valves equipped with Top Control positioners are providing precise control of water height on a water feature in the centre of Copenhagen.
The valves control 40 individual vertical water jets, each valve receiving a position signal from a central PLC to control the height of the water jets in time to music. The Type 8630 electro-pneumatic posi- tioner is designed for use with pneumati-
cally actuated control valves. With its numerous software functions, it may be used as a process controller with PID characteristics, a servo controller for process valves or as a straightforward pneu- matic positioner with either single or double acting actuators. Burkert T: 01453 731353

The V25F is an insertion style inferential flow indicator that works magnetically and gives a bright green for go or red for stopped indication of flow.
Unlike conventional inline flow indi- cators, the V25F does not suffer from dirty windows obscured by limescale rust or algae build-up. Cost effective and able to be fitted into any pipe 25mm or larger, it can even be used in effluent and highly turbid liquids. Easy to install, features incude: corro-
sion resistace; no power needed; suits pipes 25mm (1") and larger; clear bright display; no metal parts in the liquid; very high pressure rating; stainless steel and dieseline versions available. PVL T: 01892 664499
