Clamp type health target flowmeter
Description:
Products overview:
ZW - BSL series clampHealth target flowmeterIs the independent research and development production of a liquid food target flowmeter, a clamp happy connection, convenient disassembly cleaning of the flow meter, the meter is not easy to be polluted in the process of use, and can effectively prevent measure the fluid residue in the measuring tube pile up.Is a special health level of the structure of the sensor has the condensate blocking prevention, resistance to overload ability, high measurement precision, etc.It is mainly composed of measuring tube (shell), a new type of capacitive force sensor (including choke element), integrating display and output parts.According to the different medium and condition, must choose appropriate to the capacitive force sensor, therefore, provide accurate object and parameter measurement, and manufacturers can choose appropriate force of capacitance sensor is the key to accurate measurement.
Second, the structure and working principle:
1, structure,
ZW - BSL series clampHealth 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 manufacturers to choose appropriate sensor is the key of the products can be accurate measurement.
2, working principle
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 piece (target) by force (kg),
The voltage signal after preamplifier, AD conversion and computer treatment, obtains the corresponding instantaneous flow and cumulative total.
Third, scope of application:
ZW - BSL series clampHealth target flowmeterCan measure the syrup milk oil water corn starch syrup highly purified water juice wort toothpaste shampoo cleaner aromatic oil, grease and other liquid food.
Four, unique advantages:
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 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.
