Description
Ftv-1600s series
Standard vortex flowmeter
Standard vortex flowmeter
Reynolds coefficient Re> 2*104 liquid, gas, steam can be measured
The FTV-1600S series standard vortex flowmeter is researched and produced according to the Karman vortex principle to measure the volume flow or mass flow of general gas, superheated steam, saturated steam, compressed air or liquid, with small pressure loss and large range. The accuracy is high, and it is hardly affected by the fluid density, pressure, temperature, and other parameters when measuring the volume flow of the working condition. There are no movable mechanical parts, so the reliability is high and the maintenance is small. The instrument parameters can be stable for a long time, and can work in the working temperature range of -20℃～+350℃. There are analog standard signals and digital pulse signal output, which is easy to use with digital systems such as computers.

Performance characteristics
The basic principle of the FTV-1600S series standard vortex flowmeter is the Karman vortex street phenomenon. When the medium flows through the triangular cylindrical vortex generator at a certain speed, two alternating rows of vortices are formed on both sides of it. This The vortex is called the Karman vortex street. On the basis of the Karman vortex street theory, Strouhal proposed that the frequency of the Karman vortex street is proportional to the flow velocity of the fluid.
■ Corrosion-resistant stainless steel material, ABS full mold production probe simple structure
■ The detection sensor does not directly contact the measured medium, with stable performance and long life.
■ The output is a pulse signal proportional to the flow rate, without zero drift and high accuracy.
■ The pressure loss is small, the operating cost is low, and it is more energy-saving.
■ It can measure the volume flow and mass flow of steam, gas and liquid.
■ The amplifier can be separated from the sensor (separation distance 15m).
■ Using noise-canceling circuit and anti-vibration sensor head, the instrument has certain anti-environmental vibration performance.
■ The pressure loss is small, the measuring range is wide, and the range is 10-40 times
■ The measurable medium temperature can reach +350℃
■ No mechanical moving parts, long-term stability, simple structure, easy to install and maintain.
■ The output of the sensor is pulse frequency, its frequency is linear with the actual flow of the fluid being measured, the zero point has no drift, and the performance is very stable
■ Using RS-485 communication, or HART communication, can realize factory automation and integration
