1, pulse vortex flowmeter is a kind of high measurement accuracy, simple installation, small maintenance, a wide range of meters, is currently widely used in petrochemical, metallurgy, textile, urban construction, energy and other industries.
Vortex flowmeter is widely used because of its wide range, small pressure loss, medium accuracy, linear output, no moving parts, high reliability, small maintenance, medium low price, relatively high performance and price characteristics.
1. There is fluid flow in the pipeline after power-on, but no signal output
The selection of ultrasonic flowmeter should pay attention to several problems
Fixed the electromagnetic flowmeter for periodic visual inspection, check the environment around the instrument, clean dirt, ensure that no water and other substances, check whether the wiring is good, check whether the electromagnetic flowmeter near the new installation of strong electromagnetic field equipment or a new wire across the instrument.
The use of electromagnetic flowmeters is very wide, and this measuring instrument is used in many industries. Electromagnetic flowmeter is different from the general flowmeter, it follows the principle of electromagnetic induction, can measure the flow of liquid in the pipeline and its velocity.
