The company's products have always met the standards of quality and manufacturability. These criteria are no exception for liquid flow meters. Electromagnetic flowmeters have a number of advantages over analogues offered by other manufacturers:
- The devices are reliably protected from harmful effects environment;
- Operation of electromagnetic flow meters in real conditions does not cause difficulties and additional technical means;
- Durable protection from external factors that can affect the quality and stable operation of the equipment.
Electromagnetic flowmeters Takeoff will help you cope with your tasks. If you were able to quickly resolve the issue of organizing water consumption metering units, then the next step for you will be a high-quality selection of the measurement method itself and equipment specializing in this. Buyers are not always “savvy” for optimal choice and then our specialists can come to your aid.
An electromagnetic flow meter or other metering device has its own specific technical data and characteristics. This kind measuring instruments always have their own physical quantity and a small margin of error. These devices can quickly and accurately measure the volume of liquid that is passed through them. Having an electromagnetic meter in the flowmeter increases the technical accuracy of the measured medium.
Electromagnetic flowmeters Vzlet are easy to use using the electromagnetic method, which is by far the most universal and accurate. This method can easily measure pressure flows of any complexity. The essence of such a measurement is always to measure the force of electrical movement, which necessarily occurs in all flows of any liquid. A similar method was developed back in the nineteenth century, and today our modernized liquid flow measuring and metering devices will always come to your aid.
Electromagnetic counter Takeoff
Using equipment with this method always has its positive and negative sides.
Positive features and advantages of this method:
- High versatility in application;
- High stable accuracy rates;
- The quality of the measured flows does not affect the final result;
- Ease of method for measuring wastewater;
- No data loss during measurements.
The disadvantages of this method are quite minor. These include:
- The cost of electromagnetic flow meters Takeoff always depends on the diameters of the water pipes;
- In the presence of strong electromagnetic fluxes, the error scale may fluctuate.
Before making the final choice of flow meters or heat meters Vzlet, clearly define for yourself the scale of the tasks. This will allow you to correctly and wisely focus on the product range that is offered to your attention by our company. The knowledge you can gain in the field of water supply and sanitation will always help you do right choice when purchasing instruments for measuring and metering liquid flow. Good result will always be achieved with a high-quality approach to this issue and reasonable selection of equipment. A properly selected measuring device will cope with its tasks; it does not fail for a long time and is easy to use. maintenance. Each task that concerns a logical and correct measurement must always be thought out individually. And we will be happy to help you solve it!
Computer-aided development software project documentation and automatic configuration of the device according to the project. Provides the creation of a configuration base for heat meter-recorder TSR-024, -024M.
System requirements
RAM: 512 MB
operating system Windows XP, Windows 7
MS Office 2003 and higher.
Description
To create a project, it is enough to fill out information about the subscriber and a table of contractual parameters (Fig. 1).
Rice. 1
The choice of scheme is made from 10 standard templates, as well as a custom scheme (Fig. 2).
Rice. 2
Emergency situations and reactions to them are automatically installed when selecting a scheme.
Rice. 3
The pipelines are configured automatically. Depending on the selected scheme, the values of the upper and lower temperature settings are set. Contractual values of temperature, pressure, energy for heating system and domestic hot water are calculated based on a table of contractual values and parameters. The contractual volume flow values are calculated based on the contract mass flow value (Fig. 4).
Rice. 4
The flow converters are configured by selecting the flow meter model. Currently, the entire line of electromagnetic flow meters of JSC Vzlet is supported (Fig. 5).
There is also the option to create a custom template. For example, for ultrasonic flow meters, parameters included in the database are entered. Further adjustments are made during commissioning works.
Rice. 5
Upon completion of the work, a configuration base is created in the form of an MS Word document (Fig. 6), and a configuration file.
Rice. 6
The configuration file is loaded into the heat calculator, then the data is verified, which significantly reduces commissioning time.
The configuration base checksum (CRC) is calculated for all 609 basic parameters, taking into account the values they accept. Match the project checksum with the value displayed by the heat meter in the menu About the device, means complete coincidence of all parameters of the base in the device with the project created in KB TSRV-024M. The introduction of a checksum will allow you to avoid parameter verification and reduce the time of object acceptance.
