MASS FLOW METERS / REGULATORS / CONTROLLERS WITH LOCAL DISPLAY - MASS-VIEW® series

MASS-VIEW® 質量流量計/調節器/帶局部顯示屏的控制器

VA 表的高科技替代品

創新的 MASS-VIEW® 流量計系列是傳統 VA 儀表（可變面積儀表）或淨化儀表的數字替代品。 MASS-VIEW® 流量計系列採用實際氣體流量的數字條形圖，得益於 OLED（有機發光二極管）技術，從各個角度都清晰可見，並指示流量單位、氣體類型和總計數字。除了用於流量監測應用的流量計外，流量調節器和控制器還配備了一個內置針閥，用於手動控制氣體流量。作為一項額外功能，流量控制器配備了壓力補償膜，消除了上游壓力變化的影響。

MASS-VIEW 系列旨在模仿 VA 表的簡單功能和垂直格式，但具有電子輸出信號、高測量精度、幾乎不受氣體溫度和壓力變化影響、無視差誤差和通過消除流路中的易碎玻璃組件，實現了本質安全的結構。

Video MASS-VIEW Mass Flow Meter / Regulator

In this video Mass Flow ONLINE, a business unit of Bronkhorst High-Tech, the market leader in the field of thermal mass flow meters and controllers, presents the operation of the MASS-VIEW series Thermal Mass Flow Meters, Regulators and Controllers employing the direct through flow measurement technique.

Digital alternative to the conventional VA meters

It offers a standard accuracy rating of ± 2%RD if the flow is higher than 50% of it’s maximum full scale and ± (1%RD + 0.5%FS) on lower flows, handling pressures up to 10 barg (150 psi). Power consumption is low and mechanical process connections are fitted for straightforward VA meter replacement. The MASS-VIEW^® incorporates the latest OLED technology, which gives a brighter readout than LCDs, can be viewed from virtually any angle and has fast signal response times. Alarm settings and the selection of a pre-installed gas or pre-set range are accessed via a user-friendly menu, using a 4-way navigation button mounted on the front plate. An analog output signal enables data logging against various parameters and full accountability of gas flow, such as for shared ring main applications.
