Vortex Flowmeter PCL-V10
Product Overview
The PCL-V10 series vortex flowmeter is a fully intelligent flowmeter developed by combining advanced domestic and foreign technologies. It has the characteristics of simple structure, low power consumption, small resistance loss, stable operation, long durability, and easy installation.
The PCL-V10 series vortex flowmeter pays attention to every step in the process of design, material selection, process manufacturing, production assembly, and factory testing; The product has a variety of output signal forms, including standard analog signals and standard digital signal output signals, which are easy to use with digital systems such as computers and se- condary instruments, achieving the intelligence,standard-
ization, and universality of the product.
Features
■ Advanced circuit design, with both low-power amplifier and current output signal functions on the circuit board
■The product measurement range is relatively wide
■Output signal 4mA~20mA two-wire current signal corresponding to flow rate
■Display both cumulative and instantaneous traffic simultaneously
■With five stage nonlinear correction, small signal removal, and free damping time setting function
■Fully universal design, small overall size, and compact structure. Suitable for flow measurement of liquid and gas media with different diameters
■New digital filtering and correction functions make flow measurement more accurate and reliable
■Advanced humanized design, easy to operate and use
Application
■The measurement and control of compressed air and general gases (such as oxygen, nitrogen, hydrogen, natural gas, coal gas, etc.), water, and liquids (such as water, gasoline, alcohol, benzene, etc.) in industries such as petroleum, chemical, metallurgy, heating, textile, and papermaking.
