Fluidwell F116 Differential / Sum Flow Computer

The Fluidwell F116 Differential / Sum Flow Computer has been developed to calculate differential/consumption or total volume. The usual difficulties encountered in such applications include pulsating flows, very low consumption readings, vibration, and high ambient temperatures. These are all well catered for in the design and operation of the F116. The pulse and analog outputs do reflect the calculated differential or sum value.

Features

• Calculates differential flow rate (consumption), total and accumulated total of flow A and B.
• Calculates the sum flow rate, total and accumulated total of flow A and B.
• Precautions for pulsating flows and very low consumption readings.
• Analog and pulse outputs.
• Displays total and flow rate simultaneously.
• Large digit selection for flow rate or total.
• Flow rate: seven 17mm (0.67″) or 8mm (0.31″) digits.
• Total – resettable: seven 17mm (0.67″) digits.
• Accumulated total – not resettable: eleven 8mm (0.31″) digits.
• Separate engineering units for flow rate and total on the display.
• LED backlight.
• Intrinsically safe according to ATEX and IECEx.
• GRP, Aluminum or high-grade stainless steel enclosure.
• Auto backup of settings and running totals in EEPROM memory.
• Ambient temperature: -40°C to +80°C (-40°F to 176°F).
• Various accessories are available for this product.

Applications

• Differential function: fuel consumption calculation for diesel engines on board of ships or locomotives.
• Sum function: where flows are split-up in two pipe-lines and total flow has to be calculated.
• The F-Series is your first and best choice for field mount indicators in safe and hazardous area applications. Especially in harsh weather conditions like rain, snow, sandy deserts, salty atmospheres and temperatures between -40°C up to +80°C (-40°F up to 176°F).

Fluidwell F116 Differential Product specifications

• Signal Inputs
  • Flowmeter Inputs
    • Pulse-type inputs:
      Reed-switch, NAMUR, NPN/PNP pulse, Sine wave (coil), active pulse signal.
      Different pulse signal types are allowed for input A and B.
• Signal Outputs
  • Pulse outputs
    • Function: Scaled pulse output according to the bi-directional accumulated total (e.g. a pulse every 3.25 gallons).
      Max. frequency: 500Hz.
      Adjustable pulse length from 0.001 sec. to 9.999 seconds. The directional switch output is switched as soon as the pulse output reflects a “negative” quantity.
    • Type: Two passive NPN transistors, active PNP transistors or isolated electro-mechanical relays.
  • Alarm outputs
    • None
  • Analog outputs
    • Function: Re-transmitting the differential or totalized flow rate – the output can be scaled to any range (e.g. 200 L/min to 1200 L/min).
    • Type: One passive isolated, floating or loop powered 4 – 20mA output or one active (0)4 – 20mA or 0 – 10V DC output.
