Fluidwell F115 Safe Area Bi-directional Flow rate Indicator

Robust Intrinsically Safe flow computers for safe and hazardous areas. Combining easy operation and extreme durability in the toughest conditions.

The F115 has been developed for applications where the direction of flow is an issue. It is required to offer two pulse signals from the flowmeter which are 90° or 270° degrees out of phase. In case of a reverse flow, the flow rate will be displayed as a negative value, the totalizers will count down and a switch output will be set. The pulse and analog outputs do reflect both flow directions. On-screen engineering units are easily configured from a comprehensive selection.

  • 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

  • Bi-directional flow measurement applications can be found by loading and unloading of ships where one bi-directional flowmeter is used.
  • Another application is the correction for back-flow due to shocks in a pipeline caused by piston pumps or valve behavior.
  • 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).

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 positive and/or negative flow rate – the output can be scaled to any range (e.g. +40 L/min to +600 L/min and -40 L/min to -600 L/min or positive flow rates only). The 4mA / 0V equals the minimum (zero) flow rate, it can NOT equal a negative flow rate value.
      • Type: One passive isolated, floating or loop powered 4 – 20mA output or one active (0)4 – 20mA or 0 – 10V DC output.
