Description

Features

The digital vortex flowmeter is composed of a field-proven sensor and housing, and applies digital electronic technology with SSP (Spectral Signal Processing) function. We have sold more than 200,000 vortex flowmeters, and based on this, we have developed digital vortex flowmeters. Even under harsh working conditions, digital vortex flowmeters have high accuracy and stability. Due to its strong reliability and reasonable design, digital vortex flowmeter can improve the efficiency of equipment, thereby reducing production costs.

Basic technical specifications

New features with SSP (Digital Signal Processing) technology
The SSP is part of the digital vortex flowmeter circuit. SSP can analyze the fluid conditions in the digital vortex flowmeter and use the analyzed data to automatically make optimal adjustments according to the usage conditions. SSP can correctly detect vortices in low flow areas, thus significantly improving metering stability.
It can judge and display usage conditions such as large pipeline vibration and abnormal flow patterns.

High precision	±0.75% of reading (liquid) ±1% of reading (gas, steam)
wide temperature range	High temperature version: up to 450 °C Low temperature version: down to -200 °C
Simple parameter setting	Frequently used parameter combinations are placed in one module, thereby reducing parameter setting time.
Display clearly and concisely	It can display flow rate, accumulated flow rate and self-diagnosis information at the same time.
Analog/pulse dual output	Output flow signal and pulse signal at the same time
Alarm Output	If an alarm occurs, an alarm signal will be output.
Status output (flow switch function)	When an alarm occurs, the alarm signal is output by the contact. In addition, when the flow rate is lower than the set value, a signal can be output by the contact.
Converter is compact	Equipped with BRAIN/HART communication and panel setting buttons Sensors with the same structure can be used to measure liquids, gases and vapors Stainless steel sensor has no moving parts, durable and safe
Meet NACE standards	Complies with NAMUR 43 standard Maximum length of separate cable is 30m Explosionproof structure: JIS /FM/ATEX/CSA/SAA (explosionproof/intrinsically safe)

Basic performance indicators

Fluid to be measured	liquid, gas, steam (avoid multi-phase flow and adhesion)
Measuring flow range	see general specifications
Accuracy	± 0.75% of reading (liquid), ± 1% of reading (gas, steam)
Repeatability	± 0.2% of reading
Calibration	The flowmeter is calibrated with water before leaving the factory.
Normal working conditions
Fluid temperature range: – 40 ~ 260 °C (general type)	-200 ~ 100 °C (low temperature type, optional) – 40 ~ 450 °C (high temperature type, optional)
Working pressure range	- 0.1Mpa (- 1kg/cm2) ~ flange rating
Ambient temperature range	- 40 ~ 85 °C (separate sensor, separate converter) -40 ~ 85 °C (integrated type) – 30 ~ 80 °C (integrated type with meter)
Ambient humidity	5 ~ 100%RH (at 40 °C) (no condensation)
Power supply voltage	10.5 ~ 42V DC (see the relationship between power supply voltage and load resistance diagram)
Electrical performance	Since pulse output, alarm output and status output use common terminals, these functions cannot be used at the same time.
Output signal	Dual
