The large caliber plug-in turbine flowmeter is a measuring instrument with high reliability, low cost, and strong durability. It can meet the measurement of almost all liquid, gas, and steam flow rates. This flowmeter has no moving parts, strong reliability, high accuracy, and long service life. It can accurately measure the instantaneous flow rate and cumulative flow rate of liquids over a wide flow range, and is not affected by medium temperature, pressure, viscosity, or composition.

Application scenarios of large caliber plug-in vortex flowmeter

1. Measurement of gas, liquid, and steam flow in large industrial pipelines.
2. Process control and measurement in industries such as petroleum, chemical, and pharmaceutical.
3. Flow monitoring in high vibration environments.
4. In situations where sensors require frequent replacement or maintenance.

Insertion turbine flowmeter is not suitable for use in situations with strong pulsating flow, nor is it suitable for measuring mixed phase flow. Moreover, it requires high cleanliness of the measured medium, and filters need to be installed as required. However, this also increases pressure loss. The flow characteristics of small-diameter plug-in turbine flow meters are severely affected by physical properties, making it difficult to improve their performance. So before using a plug-in turbine flowmeter, it is necessary to first have a clear understanding of the working environment and the advantages and disadvantages of the product, in order to avoid affecting normal operation.

Measuring flow velocity range

Liquid	0.5m/s to 7m/s
Gas	5m/s to 60m/s
Steam	7m/s to 70m/s

Output signal of large caliber plug-in vortex flowmeter

Pulse voltage output	The parameters of high level, low level, and pulse duty cycle depend on the specific model.
Pulse current remote transmission signal	Generally, it is a 4-20mA current signal with a transmission distance of up to 1000m.

Some models also support on-site display of instantaneous flow, cumulative flow, and other parameters, and can perform compensation calculations for temperature, pressure, and other parameters.
