$3150.00 Using the patented "Time of Flight" measurement prin ciple the Thermalpulse® Flow Meter can measure almost any liquid stream with a precision of 0.1% for flow rates from 0.1 to 500 ml/min. The flow cell has no moving parts, and in our standard instruments, the only materials contacted by the stream are the stainless steel cell body, the glass coated thermistors and the Kalrez® O-rings. The cell design is very simple and cell bodies fabricated from other materials such as Teflon® and Hastalloy® can be provided. Because of this simple, no moving parts design, there is virtually no maintenance required.
The Thermalpulse control unit offers a variety of opera tional modes and display choices through easy to follow menu prompting. Monitor continuous flow, totalized volume or measure in mass units. Features include a full RS-232 and 20mA current loop computer interface as well as eight alarm relays that can be assigned to four flow or four volume set points. A 0 to 5 volt or 4 to 20 mA output provides a signal for recorders or other analog devices. Control units are available in bench top, panel mount or NEMA-type enclosures. = 198 8. Moiytek, INC.
