This article is reproduced from: http://www.china-yokogawa.com/News/237.html. Keywords of this article: Yokogawa mass flow meters. There are many types of Yokogawa mass flow meters, which can be used in various fields. There are three common types, such as: compensating mass flow meters, direct mass flow meters, and derived mass flow meters. Next, the editor will introduce these 3 products to you. 1. The compensating Yokogawa mass flow meter can simultaneously measure the temperature and pressure of the fluid as well as its volumetric flow rate. The mass flow rate of the fluid is calculated by a computing unit, and the density of the fluid under those conditions is also determined, based on the relationship between fluid density and temperature and pressure. 2. Direct-type mass flowmeters: There are various types of Yokogawa direct-type mass flowmeters, such as angular momentum type, dual impeller type, calorimetric type, and gyroscopic type. Its sensing element can directly reflect the mass flow rate, and it can directly measure a flow value that is proportional to the mass flow rate. However, since the measuring element is in contact with the medium, it is prone to corrosion and contamination, and has low reactivity; it is mainly suitable for measuring small-flow gases. 3. Derivative mass flow meter: The derivative Yokogawa mass flow meter typically uses a combination of a volume flow meter and a density meter to measure mass flow; by performing calculations, it generates an output signal related to the mass flow, allowing for the simultaneous detection of both the fluid density and volume flow. There are mainly 3 types: a combination of a throttling flow meter and a densitometer, a combination of a densitometer and a velocity flow meter, and a combination of a volumetric flow meter and a throttling flow meter.
