Can a metal rotor flowmeter be selected based on the five product elements?

Project Overview

For the selection of flow meters, it is often heard that there are three factors of working conditions: medium, temperature, and pressure. In fact, the five elements of the product are also very important for model selection. This article will introduce to you what are the five elements of products.

Element 1: Caliber

Metal rotor flow meters can only measure the flow of small-diameter pipes, and cannot measure pipes exceeding 200mm. Of course, not all small pipes can be measured, and the smallest diameter that can be achieved is 15mm. Standard pipe diameters between DN15 and 200 can be matched.

Element 2: Power supply

The metal rotor flowmeter can meet both 220VAC alternating current and 24VDC direct current models. There is also a more economical pointer direct display type. This metal rotameter does not require an external power supply. In addition, there is also a model powered by lithium batteries.

Element 3: Material

The liquid-contacting materials of the metal rotor flowmeter sensor include 304 stainless steel, 316 stainless steel, 316L stainless steel, titanium Ti and PTFE-lined ones. The corresponding Different media.

Element 4: Output signal

The standard output signals of 220V and 24V power supplies are both 4-20mA current signals. However, both the battery type and the pointer direct display type do not have signal output. Special models can be equipped with lower limit alarm and pulse output.

Element 5: Measuring range

Metal rotor flowmeters with the same caliber can measure liquid volume flow and gas volume flow in different ranges. The float model selected for the same caliber Different, the measurement range is also different. When selecting models, manufacturers generally ask about the regular flow rates on site to make product recommendations.

The five major factors mentioned above are related to flow meter products, but they are also closely related to specific working conditions.
