The Model PD765 Trident Meter is an all new Universal Panel Meter that handles all the common process display applications with simplicity, reliability, accuracy and ease. It is factory calibrated to accept process voltage and current inputs, 100 ohm platinum RTDs and the four most common thermocouples. Setup and programming is a jumper-free, single switch, snap using the simple four-button programming method or a computer. And if there are multiple meters to be programmed, the Trident's Copy capability allows one meter's setup to be automatically copied to another meter.

Model F012 Flow Rate and Totalizing Display

click to enlarge


The F012 display is a basic flow rate and totalizing display. The total and flow rate are displayed together with large 0.67” (17mm) digits and smaller 0.31” (8mm) digits along with the units of measurement. Pressing the clear button twice will clear the running total. Accumulated total is shown after pressing the select key. The F012 has optional inputs including Pulse, Coil, NAMUR, 4-20 mA or 0-10 V. The F012 is offered with a plastic, aluminum, or explosion proof enclosure, or it can be ordered to simply panel mount. The options for powering the unit are battery, IS battery, loop power, 80-240 VAC with sensor supply, IS 16-30 VDC, and 8-24 VAC/VDC. The F012-XI can be used in hazardous areas too, classification EEx ia IIB T4.

  • Simple but flexible display shows both flow rate and total
  • -40 to 80°C operational temperature
  • 7 Digit LCD display offered with backlight
  • 11 Digit Accumulated total with engineering units
  • Available with numerous enclosure options and minimal depth requirement
  • Clear menu structure that is universal across line
  • Contains 7 Digit K-Factor for tuning
  • All settings are stored in EEPROM for power failure protection
  • Differing measuring units may be chosen for flow and total
