Starflow Accessories

To simplify use and get most out of Starflow ultrasonic Doppler instrument following components can be added.

The Starflow 6526C-LCD HSIO LCD display unit interfaces with the 6526 Starflow ultrasonic Doppler velocity, depth and flow Instrument. It displays the values obtained from the most recent scan.

Starflow’s scheme defines which parameters will be displayed. For example, one of the supplied schemes displays water temperature, battery supply voltage, totalised flow and logging status. The 6526 LCD is packaged in a compact weatherproof polycarbonate enclosure, fitted with pre-wired SQL type
connectors. These connectors enable direct connection to a Starflow instrument, and computer/external power supply using a 6603D-SDI cable.

The SQL connections are designed to be ‘pass through’ so that the computer can connect to the instrument without disconnecting the power or display.

The display module power supply can be wired to a user-installed switch so that it can be switched on only when necessary. The module display is refreshed every scan (normally 15 seconds with a Starflow) and will display a text message when power is applied until a message from the instrument is received. Pressing the button on the front panel resets the display.

Microwire serial to 4-20mA Interface 6122C-S converts a serial signal to a 4-20mA output. Any microwire compatible 3-wire synchronous serial signal channel can be used as an input. It supports two 16-bit resolution channels. The Starflow supports microwire as an alternative use of the SDI-12 channel. This enables the connection of any measured channel to a 4-20mA transmitter.

The 6702S and 6702S-LCD weatherproof polycarbonate enclosures contain mounting hardware for a 12V 14Ah sealed lead-acid battery 6907B-14 and drying tube 6603DT. There are three SQL connectors mounted in the base of the enclosure. These are wired to enable connection to the Starflow, PC and solar panel/external power. The 6702S-LCD has an LCD mounted on the hinged lid of a large weatherproof polycarbonate enclosure.

It displays the values of parameters obtained from the most recent scan as defined by Starflow scheme. The LCD unit communicates with the Starflow via the HSIO bus. The RS232 interface is available for other purposes such as connecting a modem.

To keep the vent tube and vented-cable dry, a drying tube 6603DT containing “silica-gel” desiccant is connected to the Starflow cable using special Tygon tubing. The drying tube needs to vent to the atmosphere. Drying tube should be replaced when silica-gel turns pink – (normally blue)

The Starflow adaptor cable 6603D-SDI is communication cable that allows you to connect Starflow to a PC and a 12V battery.

Stainless Steel Mounting Bracket Model 6526M-2 is a clamp used to secure a Starflow instrument into a channel or a pipe. The bracket saddle locks the instrument into its correct position.

The Model 6705 expanding band kit allows you to install a Starflow instrument in pipes of different sizes. The band is flexible enough to fit irregular shapes such as ovoid sections. All components are made from stainless steel and the band fittings are 100mm wide to match the 6526M-2 mounting bracket.
