Description：
Products overview:
ZW - BSL seriesHeat preservation jacket target flowmeterIs my company production for viscosity is too large, such as asphalt, condensate will crystallize, frozen liquid flow measurement of flange connection type flowmeter, outside the measurement subject to install a heat preservation jacket, constitute bubbled into steam and hot agent can make the liquid being measured normal circulation.Adopt mature and reliable force weighing sensor technology, the demand according to the working condition characteristics, flow velocity and flow rate can be (or will be working temperature and pressure detection integration optimization), fully embodies the modern electromechanical integration products of high technological and product price.Instrument system data processing using modern microelectronic technology research and development of new technology and a high reliability, high accuracy of industrial flow measurement and control instrument.
Second, the structure and working principle:
1, structure,
ZW - BSL series insulation jacket target flowmeter is mainly composed of measuring tube (shell), new sensors (including choke element), integrating display and output parts.According to the different medium and condition, must choose appropriate sensors, therefore, provide accurate object and parameter measurement, and manufacturers to choose appropriate sensor is the key of the products can be accurate measurement.
2, working principle
Target flowmeterIs when the media in the measurement of pipe flow, because of its kinetic energy through the choke a target flowmeter) (sometimes produce pressure difference, and the choke a force, its size and medium force is proportional to the square of the velocity of flow, the mathematical expression is as follows:
F = CdA rho?V2/2,
Type: F choke a force (kg) of
Drag coefficient Cd object
A choke pieces on the measuring tube axial projection area (was)
Rho conditions of medium density (kg/m3)
V medium in the measuring tube average flow velocity (m/s)
Choke (target) accept force F, the rigid connection of transfer (rod) to the sensor, the sensor produces voltage signal output: V = KF
Type: V - sensor output voltage (mV), K - proportionality constant, F - choke piece (target) by force (kg),
The voltage signal after preamplifier, AD conversion and computer treatment, obtains the corresponding instantaneous flow and cumulative total.
Applications:
ZW - target flowmeter BSL series insulation jacketAlternative to conventional flowmeter and conventional fluid flow measurement, especially in high viscosity, easy to mountains, high temperature and high pressure, strong corrosion and other flow metering has the very good application value in difficult condition, at present has been widely used in steel, oil, natural gas, electric power, papermaking, chemical, energy, food, environmental protection and other fields of flow measurement.
Four, the main features:
1, the whole instrument have no moving parts in the design, installation is simple and maintenance-free;
2, USES the advanced third generation capacitive force sensor, reliable performance, accuracy, high sensitivity;
3, small pressure loss, is only half of the standard orifice plate around the delta P;
4, resistant to dirt, non-clogging, resistance to vibration, electromagnetic interference, strong ability to resist the impurities, and alternative differential pressure flowmeter;
5, can choose a variety of corrosion and high temperature resistant material (such as hardox alloy, titanium, etc.);
6, the machine can be made into full seal no dead Angle (welding), no leak, resistant to 42 mpa pressure;
7, instrument with self-checking program, failure phenomenon be clear at a glance;
8, sensors, not contact with the measured medium, there is no parts wear, use secure and reliable;
9, can be used on-site dry calibration method, hang heavy weights method is adopted.A single bond operation can complete calibration;
Select 10, has many installation modes, such as choosing the online plug-in installation cost is low;
11, with the integration of temperature and pressure compensation, direct output quality or the party;
12, with optional small signal excision, nonlinear correction, filtering time can choose;
13, can accurately measure all kinds of room temperature, high temperature, low temperature of 500 degrees - 200 degrees conditions of gas and liquid flow;
14, measuring accuracy, the accuracy can reach 0.2%;
15, good repeatability, average of 0.05 ~ 0.08%, and quickly;
16, according to actual need to replace choke parts (target) and change the flow range;
17, low-power battery scene shows, can online direct reading values, instantaneous in screen can read at the same time and cumulative flow and percentage of stick figure;
18, simple and convenient installation, easy to maintenance;
19, multiple output form, can remote transmission parameters;
20, seismic resistance is strong, measurable pulsating flow within a certain range.
