LZZH-150 LZDH-150 Metal tube rotameter

Overview

LZZH-150 LZDH-150 Metal tube rotameter has indication type, electric remote transmission type, corrosion-resistant type, high-pressure type, jacket type and explosion-proof type. With 0-10mA, 4-20mA standard analog signal output and field indication. Accumulation, digital communication, on-site modification of measurement parameters, different power supply functions, with magnetic filters and special specifications. Widely used in petroleum, chemical, power generation, pharmaceutical, food, water treatment, etc. In the process of flow measurement in complex, harsh environmental conditions, and various media conditions.

Working principle of LZZH-150 LZDH-150 Metal tube rotameter

The working principle of Metal tube rotameter: The flow is measured according to the height of the metal tube float in the conical tube, and the weight of the float is balanced by the pressure difference generated when the fluid passes through the gap between the float and the tube wall. The higher it is supported, the larger the annular gap area, that is, the annular gap area changes with the flow rate, so it is generally called the area method. type of transmitter or transmitter.
