Master-Touch™ 800HPN Features
Master-Touch Series 800HPN Flow Meters are In-line style instruments with all electronics mounted integrally on the flow section in a Type 4X, IP66 enclosure. All input power and signal output connections are accessible through this double-sided enclosure. The Series features a VCR style sensor for easy removal and cleaning. The internal wetted surfaces may be electro-polished to either a 10 Ra or 25 Ra surface finish. Inlet flow conditioning plates are optionally available on flow sections from ¾” to 6”. Mounting is via butt weld ends.
Optional end configurations include – Tri-Clamp style ends or male VCR style ends for ½”, ¾” or 1” tubes.
A 2-line, 16-character LCD display with a 4-button keypad, displays the flow rate, totalized flow total, gas temperatures, electronics temperatures, sensor milliwatts, event/alarm relay status. It also provides access to the menuing system for change of user accessible variables. Included are 0–5 VDC and 4-20 mA outputs proportional to flow, as well as RS232; RS485; Modbus RTU; BACnet communications.
Currently no agency approvals.
