Product Details
Description:

Products overview:
ZW - BSL seriesWith ball valvePlug in the target flowmeterAdopt 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.The target flowmeter system data processing using MCU technology combined with modern microelectronic technology research and development of a kind of high reliability, high accuracy of industrial flow measurement and control instrument.

Second, the structure principle:
1, the structure:
ZW - BSL seriesWith ball valvePlug in the target flowmeterMainly by the 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 the manufacturer chooses the appropriate sensor is the key of the products can be accurate measurement.
2, how it works:
When the medium in the measurement of pipe flow, because of its kinetic energy through the choke a (target flowmeter) sometimes produce pressure difference, and there is a force to choke a, size of the force is directly proportional to the square of the velocity with the media, its mathematical expression is as follows:
CdA rho V2 / F = 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 a (target) by force (kg),
The voltage signal after preamplifier, AD conversion and computer treatment, obtains the corresponding instantaneous flow and cumulative total.
Applications:
ZW - BSL seriesWith ball valvePlug in the target flowmeterIs mainly used to solve the high viscosity, low Reynolds number fluid flow measurement, has experienced the pneumatic tables and electric table two stages of development, has been widely used in semi water gas, coke oven gas, heavy oil, residual oil metering, asphalt, liquid paraffin, toluene, sulfuric acid, natural gas, methane chloride, flue gas, sewage, water, etc, and other special medium measurement, resolves the problem for many years the industry flow metering.
Four, the main features:
1, have no moving parts, in the design of the whole station instrument in the insert structure, convenient disassembly;
2, can choose a variety of corrosion and high temperature resistant material (such as alloy, titanium, etc.);
3, the machine can make the whole sealing no dead Angle (welding), no leak, resistant to 42 mpa pressure;
4, instrument with self-checking program, failure phenomenon be clear at a glance;
5, sensors, not contact with the measured medium, there is no parts wear, use secure and reliable;
6, can be used on-site dry calibration method, hang heavy weights method is adopted.A single bond operation can complete calibration;
Select 7, has many installation modes, such as choosing the online plug-in installation cost is low;
8, with the integration of temperature and pressure compensation, direct output quality or the party;
9, with optional small signal excision, nonlinear correction, filtering time can choose;
10, can accurately measure all kinds of room temperature, working condition of high temperature, low temperature of 500 degrees - 200 degrees, the gas and liquid flow;
11, accurate measurement, the accuracy can reach 0.2%;
12, good repeatability, average of 0.05 ~ 0.08%, and quickly;
13, the pressure loss is small, only about 1/2 delta P standard orifice plate;
14, anti-interference, impurity resistance strong;
15, can according to the actual need to replace choke (target) and change the flow range;
16, low-power battery field shows that can direct reading online, value for display can be read at the same time instantaneous and cumulative flow rate and the percentage of stick figure;
17, simple and convenient installation, easy to maintenance;
18, multiple output form, can remote transmission parameters;
19, seismic resistance is strong, measurable pulsating flow within a certain range;
Five, the technical parameters:
