1. INTRODUCTION TO THE FUH1010PVX/DVDX NEMA-7 FLOWMETER
Congratulations on purchasing the FUH1010PVX/PVDX NEMA-7 flowmeter. For use in dedicated appli-
cations, the FUH1010PVX utilizes the latest “cutting edge” technology yet is easy to setup and use. It will
not take long for you to appreciate its unmatched performance and its many features such as the
unique enhanced transit-time digitally coded MultiPulse
TM
technology.
THe FUH1010PVX is a compact NEMA-7/EExd-rated explosion-proof transit-time flow computer. Func-
tionally, it’s similar to the standard FUS1010N NEMA-4X flow computer and operates as a stand-alone
meter using conventional clamp-on transducers or in-line tubes.
1.1 SYSTEM HARDWARE DESCRIPTION
FUH1010PVX is housed inside a cylindrical explosion-proof NEMA-7 aluminum, epoxy painted case. The
main metering compartment front and rear sections are sealed with an O-Ring with separate threaded
covers. The front section houses the main electronics and the optional Magnetic Touch-Panel User Inter-
face with a 2 x 16 character LCD Alphanumeric Display viewable through a tempered glass window. The
rear section contains terminal blocks for the fused power input and data I/O wiring. The primary instru-
mentation output is an isolated 4-20 mA current loop. The meter includes a conventional RS-232 I/O
port.
The main metering compartment is connected to the secondary housing by an aluminum pipe that
provides a pass-through for flow transducer and temperature sensor cabling. The secondary housing
provides screw-on wire clamp terminals for flow and temperature sensors. To maintain the NEMA-7
explosion-proof rating, all cabling and the transducer physical and electrical design must be in compli-
ance with hazardous area specifications.
Power Consumption 110/220 VAC, less than 10 Watts; 9-36 Vdc
G-Force Rating Instrument survives 3” drop onto 1” plywood (standard industrial
drop test). Mechanical design supports operation in a high
vibration environment.
For Hazardous Area Use Explosion-proof case designed for installation in Division 1/Zone
hazardous environments when installed per our instructions.
Agency approvals: CE (for EM) and FM/CENELEC pending.
International approvals pending.
Provisions for User Menu Access Magnetic triggers (4- Enter).
RS-232 Interface for menu access and datalogger dump.
Options Dial-up Modem
One RTD temperature sensing channel (measures clamp-on
liquid temperature)
Blind System (programming via serial link only)
