Steam Flowmeter / Saturated Steam Flowmeter Vortex Flowmeter With Temperature And Pressure Compensation
Introduction
Turbine flowmeter is a kind of velocity flowmeter with temperature and pressure compensation function. It belongs to one kind of velocity flowmeter. Its working principle is as follows: the power of flowing fluid drives the turbine blade to rotate, and its rotation speed is approximately proportional to the volume flow rate. Turbine flowmeter is widely used in petroleum, chemical industry, electric power, gas pipe network, urban gas and other fields, and is widely used in trade settlement because of its high measuring accuracy, good repeatability and stability, wide range, rapid response to flow changes, strong anti-interference ability, easy signal transmission and other characteristics.
KVF series eddy current flowmeter adopts advanced differential technology, combined with isolation, shielding, filtering and other measurements, with better vibration resistance and signal stability.
Features
1. Detecting element does not touch with flow medium, with high reliability and strong flexibility for medium
2. No moving parts, wear resistance, structure is simple and fastness
3. Assemble with anti-interference circuit and anti-vibration sensors, which could ensure anti-vibration performance of the product.
4. The allowed working temperature is wide from -40℃ to +350℃
5. Wide range, High accuracy
6. Pulse signal output or two-wire system 4-20mA current signal output
