| Click to download V cone flowmeter Manual V-cone flow sensor (referred to as V
cone) is a new differential pressure flow measurement devices, it
is a unique side wall of the gradual contraction throttle, a device
to change the traditional throttle almost all the defects in the
differential pressure meter revolutionary results. The principle
the same as with other differential pressure flow meter is a
classic closed pipe flow of energy conservation principle and the
continuity principle and self-rectification, self-cleaning,
self-protection performance; straight pipe, which asks for a very
short, non-product pollution, congestion, can maintain long-term
measurement stability; cone back-end high-frequency low-amplitude
limit of small noise, so that measurement is relatively low, so
that turndown ratio up to 15:1; the permanent pressure loss and the
plate is only 1 / 3 and Venturi tubes similar to . Therefore, V
cone can be widely used in petroleum, chemical, electric power,
heating and other areas of the national economy, the measurement of
liquid and gas media, measurement. Features
structure
Flange clamp-type
Suitable for small diameter pipeline measurement, ease of
installation. Especially for non-metallic or other special
materials manufactured from time to time.
Precision Measuring tube
Is the widespread use of the structure, which will help
calibration, installation, use and measurement, the general
recommendation of this model.
Pipe Butt Type: On-site installation convenience, more applicable
to high-pressure situations.
Dual-flange to take pressure type
Suitable for high viscosity, stains, corrosion, cleaning and easy
crystallization, freezing and other media, supporting the use of
capillary pressure differential pressure transmitter flange to
take, without laying pressure pipe.
Transmitter holistic style
Transmitter connection with the V cone as a whole, without laying
pressure pipe to reduce the risks of failure, allowing users to
install, use more convenient.
Features
Self-Protection
As the fluid in the cone formed on the surface of the boundary
layer effect, so that the surface to be protected cone, cone
critical dimension will not be changed due to wear and tear,
ensuring long-term stability of the measurement accuracy.
Since the rectifying behavior
As the sharp cone center in the pipeline, forcing fluid to the
annular wall of a gradual contraction, so that flow through the
cone to achieve rectification, without the full development of
calibration can reproduce the real time data, on-site straight pipe
requirements are very short, this great advantage of other
flowmeters can not do, in the practical application of the
revolutionary.
Self-cleaning feature
As the fluids along the cone is accelerated, dirty impurities can
not be retained cone surface; liquid gas or gas in the liquid and
particles, fibers, etc., through the cone and the gap was down the
pipe downstream, there will be no stain, impurity retention, plug
affect measurement instrument can guarantee the long-term
stability.
wider range
As the cone special structure so that negative pressure zone is
generated by a small high-frequency low-amplitude noise, the
relative plate to take its suction pressure disturbance is very
small, which can detect more small differential signal, so that
range can be achieved than 15:1. Specifications
