Oil Industry / Chemical Industry Vortex Flowmeter with Explosion
Proof
1. Introduction
LUGBML is based on Von Karman’s Vortex Principle, which adopts
piezoelectric crystal as testing components. It is a new kind of
stress detecting vortex flow meter. It has the advantage of wide
range ratio, high accuracy, low pressure loss, good medium
generality, pulse output proportional to flow, convenient to
connect with computer and etc. As the detector probe of sensor and
the vortex generating body are installed separately, and the high
temperature resistant piezoelectric crystal doesn’t contact with
medium, so the instrument is of simple structure, good generality
and high stability.
LUGBML series Vortex Flow Meter sensor can be used to detect and
measure the flow of all kinds of gas, liquid and steam.
LUGBML series Vortex Flow Meter can be used to match with our
company’s ML6000 series Velocity Flowmeter. It can also match with
a computer and sensors of temperature, pressure, or density to
compose high accuracy mass flow or heat flow detecting and
measuring system.
2. Application
LUGBML series is suitable for oil,chemical
industry,metallurgy,heating power,spinning,paper making ,etc. Be
use of control: over-heating vapor, saturation vapor, compressed
air,ordinary air(oxygen, nitrogen, hydrogen, natural gas, coal gas
,etc),water and liquid (water, petrol ,alcohol, benzene ,etc.)
