Fluidwell Totalizer F115 Flow Rate Indicator

Definisi Fluidwell Totalizer F115 Flow Rate Indicator

Fluidwell Totalizer F115 Flow Rate Indicator telah dikembangkan untuk aplikasi di mana arah aliran menjadi masalah. Diperlukan untuk menawarkan dua sinyal pulsa dari flowmeter yang 90° atau 270° derajat di luar fase. Dalam kasus aliran balik, laju aliran akan ditampilkan sebagai nilai negatif, penghitung akan menghitung mundur dan keluaran saklar akan diatur. Output pulsa dan analog memang mencerminkan kedua arah aliran. Unit teknik di layar mudah dikonfigurasi dari pilihan yang komprehensif.

Fitur

• Quadrature input to detect the direction of flow.
• Displays positive and negative flow rate to indicate the flow direction.
• Total and accumulated total count up and down according to the flow direction.
• 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 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.

Aplikasi

• Aplikasi pengukuran aliran dua arah dapat ditemukan dengan bongkar muat kapal di mana satu flowmeter dua arah digunakan.
• Aplikasi lain adalah koreksi aliran balik karena guncangan dalam pipa yang disebabkan oleh pompa piston atau perilaku katup.
• F-Series adalah pilihan pertama dan terbaik Anda untuk indikator pemasangan di lapangan dalam aplikasi area aman dan berbahaya. Terutama dalam kondisi cuaca yang keras seperti hujan, salju, gurun berpasir, atmosfer asin, dan suhu antara -40°C hingga +80°C (-40°F hingga 176°F).

Produk Spesifikasi

• Sinyal 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.
• Sinyal 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.
• Suplai
  • Power Supply
    • Long life Lithium battery.
    • 4 – 20mA Output loop-powered.
    • 8 – 24V AC/DC.
    • 115 – 230V AC.
    • Basic: 8 – 30V DC.
  • Sensor Supply
    • 3.2, 8.2, 12, 24V DC.
• Hazardous Area
  • Intrinsically Safe
    • ATEX:
      Gas: II 1 G Ex ia IIB/IIC T4 Ga
      Dust: II 1 D Ex ia IIIC T100 °C Da
    • IECEx:
      Gas: Ex ia IIC/IIB T4 Ga

      Gas: II 2 G / Ex d IIB T5 Gb
      Dust: II 2 D / Ex t IIIB T100°C Db
• Komunikasi
  • Function: All process data and settings can be read and modified through the communication link.
  • Protocol: Modbus ASCII / RTU.
  • Interface: RS232 / RS485 2-wire or 4-wire / TTL.
  • HART communication is available with the F018 & E 018 Flow rate Monitor / Totalizers.
