Flow meter gas aichi tokei

Definisi Gas Meter

Alat untuk mengukur kuantitas atau laju aliran gas. Jenis meter gas (berdasarkan prinsip operasi) termasuk perpindahan, kecepatan, kepala, termal, akustik, dan pelacak. Contoh dari prinsip perpindahan adalah meteran gas bellow-dan-diafragma (ditunjukkan dalam diagram).

Tubine gas meter / flow meter gas turbine

Selama pengukuran, molekul gas cenderung berjalan melalui meteran secara terus menerus, yang menghasilkan denyut selama kalibrasi. Peredam suara dapat digunakan untuk menghindari kesalahan pengukuran yang signifikan.Sistem roda gigi, roda turbin, bagian ekstrusi, dan unit rumah tertutup adalah komponen utama meter turbin.Saat gas mengalir, roda turbin mulai berputar. Putaran roda turbin sebanding dengan kecepatan aliran. Oleh karena itu, volume gas dapat dihitung sehubungan dengan putaran roda.

Deskripsi

Features

Turbine meters in the TBZ and TBX series were developed for controlling the gas consumption of each piece of equipment such as compact boilers and various industrial furnaces.

The products realize a smart design with a lightweight and compact body and support a wide range of measurement including maximum working pressure and maximum measuring flow rate.

Furthermore, the built-in 2-system pulse transmitters enable you to establish a remote meter reading system and an energy control system.

The TBZ series even corrects temperature and pressure to allow you to read gas consumption in the standard conversion condition.

The external power supply model TBX-D has been newly added to the lineup of the TBX series. You can choose the model that would best suit your applications for better usability.

The maximum working pressure covers low, medium and high pressures.
・Free installation positions.
・Equipped with two systems of pulse transmitter.
・Supports a variety of gases and a wider range of applications.
・LCD display that gives you more information.
・Corrects temperature and pressure. (TBZ series).
・Non-stop operation for seven years. (For the battery specifications)

Application examples
. Manage and control gas flows of burning equipment such as burners, boilers and furnaces.
・Manage and control flows of hot and chilled water generators in compact to medium sizes.
・Manage and control flows of gas refrigerators.
・Manage and control gas flows as a part of plant instrumentation.
・For various experimental devices relating to gas flows.
