Fine Tek Level Transmitter

10.RF-Capacitance Level Transmitter-EB Series

RF-Capacitance Level Transmitter

Principle
Capacitance
Level Indicator: Utilizes the capacitance formed between the sensing
probe and the metallic vessel wall. A high frequency sine-wave is
applied between the probe and the vessel wall.
A change of the medium level will induce a change in the current of the applied sine wave.
From
Z=1/2pfc, when the capacitance in the vessel increase, impedance will
decrease and current will increase. Vice-versa, when the capacitance in
the vessel is small, the impedance will increase and current will
decrease accordingly.

    proportional to the liquid level. Also, the float level indicator can be
    equipped with the TAB-1531 (please see page 3) to produce a 0/4~20mA
    signal. In addition, we can use with PB series bargraphic display
    scaling panel meter for level control and display. Anyway, “Magnet Float

Penentuan Kapasitas Flow Meter Pada Aliran Air

Flow meter merupakan alat instrument untuk mengukur kapasitas aliran suatu fluida baik aliran dalam pipa yang merupakan rangkaian tertutup maupun rangkaian terbuka seperti pada channel atau parit atau sungai. Penentuan Kapasitas flow meter harus di dasarkan pada Kapasitas aliran yang akan di ukur. Dalam menentukan kapasitas flow meter ada hal yang mendasar harus di pertimbangkan yaitu besarnya flow velocity. Flow velocity ini memegang peranan peting ayang akan mengakibatkan perubahan variable terhadap besarnya nilai investasi dan besarnya biaya Maintenance. Hubungan antara kapasitas flow rate yang direncanakan sebaiknya mempertimbangkan besaran flow velocity, karena untuk flow velocity yang besar akan berakibat pada biaya maintenance dan konstruksi  yang mahal. Begitu juga jika kita menggunakan desain dengan velocity yang rendah menyebakan biaya investasi piping yang tinggi karena banyaknya pipa yang digunakan pada sitem. Mahalnya investasi ini dikarenakan perlunya sistem konstruksi yang prima karena adanya faktor pressure yang tinggi, back pressure pada jalur tikungan atau cross joint serta peralatan instrument yang mempunyai spesifikasi tinggi. Kapasitas flow meter sebenarnya didasarkan pada luasan penampang pipa yang dikalikan dengan velocity, dimana semakin besar velocity akan berakibat naiknya kapasitas dan diperlukan pressure yang tinggi dan kontruksi pemipaan yang tinggi pula. Flow velocity dari flow meter pada umumnya berada pada kisaran […]
