Difference between vortex flowmeter and turbine flowmeter

What is the difference between a vortex flowmeter and a turbine flowmeter? In the case of the same performance, which one is more cost-effective?

Parameters: medium: cold water and boiling water, temperature: 120 degrees, pressure: 4.0 MPa, caliber: 20 MM, 485 communication.

A: These two price/performance ratios are similar. Their shackles: vortex flowmeters can't have signal interference, and anti-vibration can't. The liquid turbine flowmeter is to ensure that the measurement medium is free from any impurities.

Vortex flowmeters are also known as vortex flowmeters or Karman vortex flowmeters. Comprehensively absorbing the advanced technology of developed countries and summarizing the research and production experience for many years, the products have been carefully designed to realize the product intelligence, standardization, serialization, generalization, production and mold, and ensure the beauty of product quality. The product has the characteristics of advanced circuit, low power consumption, wide range ratio, simple structure, small resistance loss, sturdy and durable, wide application, long service life, stable operation and easy installation and debugging.

The liquid turbine flowmeter is a new flowmeter display instrument designed with advanced single-chip microcomputer technology, which is matched with flow sensor (such as turbine and vortex) for pulse signal output. Instantaneous flow and cumulative total can be displayed. Cumulative flow: eight digits, three significant digits after the decimal point. Instantaneous flow: A six-digit number that shows the change per liter. Display accuracy: ± 1 display unit. Signal output: Pulse output: 1~3000Hz external supply +12~+24VDC power supply Current output: 4~20mA external supply +24VDC power supply (two-wire system) Built-in 2 3V lithium battery in parallel. Undervoltage indication occurs when the voltage is lower than 2.7V, and the explosion-proof type. Small signal removal function.

Technical characteristics
High precision, generally up to high precision
Good repeatability, short-term repeatability of 0.05% to 0.2%, due to good repeatability, such as frequent calibration or online calibration can get very high accuracy, is the preferred flow meter in trade settlement;
Output pulse frequency signal, suitable for total metering and connection with computer, no zero drift, strong anti-interference ability;
A very high frequency signal (3~4kHz) can be obtained, and the signal resolution is strong;
The range is wide, the medium and large caliber can reach 1:20, and the small diameter is 1:10;
Compact and lightweight, easy to install and maintain, and large in circulation capacity;
Applicable to high-pressure measurement, it is not necessary to open holes on the meter body, and it is easy to be made into high-pressure type instrument;
There are many types of special-purpose sensors, which can be designed into various types of special-purpose sensors according to the special needs of users, such as low-temperature type, two-way type, downhole type, sand mixing type, etc.; can be made into insert type, suitable for large diameter measurement, with small pressure loss. The price is low, it can be continuously taken out, and the installation and maintenance are convenient.
