Flowmeter-meter ESKO-RV.08 electromagnetic
Flowmeter-meter ESKO-RV.08 electromagnetic consists of a full-bore electromagnetic primary flow converter (PPR) and a measuring unit (IB), combined into a monoblock.
Flowmeters ESKO-RV.08 are available in designs which are different:
According to the design of the PPR:
- PPR with flange connection (basic version);
- PPR with flangeless (bayonet or threaded) connection (optional).
According to the design of IS:
- IS without display (basic version);
- IB with remote display (optional).
The principle of operation of the e / m flowmeter ESKO-RV.08 based on the phenomenon of electromagnetic induction. When passing through an electrically conductive
liquid through a magnetic field with magnetic induction B, in it, as in a moving conductor, an electromotive force EMF proportional to the velocity of the liquid is induced.
EMF is removed by two electrodes located diametrically opposite in one cross section of the PPR pipe.
The signal from the PPR is fed by shielded wires to the input of the IB, which provides its further processing.
The EMF value does not depend on the temperature, viscosity and conductivity of the liquid, provided that the conductivity is in the range from 10-3 to 10 S/m at a temperature of 0 to +150°C and a pressure of 0.1 to 2.5 MPa.
Operating conditions and parameters of the working environment of the flowmeter ESKO-RV.08

Flowmeter-counter ESKO-R digital electromagnetic with RS485 interface
Flowmeter-counter ESKO-R digital electromagnetic designed for continuous measurement of volumetric flow rates and volumes of liquid electrically conductive media. ESKO-R flowmeters allow measuring the flow and volume of liquid both in the forward and in the reverse (reverse) direction.
Flowmeter ESKO-R is a component product, and includes:
- primary flow converter - electromagnetic and computational-measuring unit (CME), combined into a monoblock;
- overpressure sensors (may not be used);
- resistance thermocouples (may not be used).
The principle of operation of electromagnetic flowmeters ESKO-R is based on the phenomenon of electromotive force (EMF) induction in a moving magnetic field conductor - the medium being measured. The induced EMF, the value of which is proportional to the flow rate of the medium being measured, is perceived by the electrodes and enters the computing and measuring unit (CMU), which performs signal processing, calculation of volume flow and volume and converts it into standardized analog and digital output signals. The BVI of the ESKO-R flowmeter has two inputs for connecting resistance thermocouples (sets of resistance thermocouples with nominal static conversion characteristics (NSKh 100P, 500P, 1000P, Pt100, Pt500, Pt1000) and two inputs of the "current loop" standard with a shifted range from 4 to 20 mA for overpressure sensors The results of measurements of temperature and overpressure of the coolant are formed in the BVI in the form of a digital output signal.
To connect to a power source and recording devices, ESKO-R flowmeters can have one, two four-pin din connectors or one four- and one three-pin din connector, depending on the availability of enabled communication interfaces.
Functionality, features and advantages of the ESKO-R digital flowmeter:
— RS-485 interface, which allows you to connect flowmeters into a network in order to transmit information about the results of measurements by means of a digital (discrete) coded signal;
- the event log;
— especially precise executions;
— increased average service life and time between failures;
- Possibility of direct current supply 24 V;
- Warranty period - 18 months.
Output signals and presentation of measurements of the ESKO-R flowmeter
Flowmeters ESKO-R provide the presentation of measurement results in the following form:
- output frequency signal of a rectangular shape with a programmable frequency directly proportional to the flow rate;
- output pulse signal with a programmable weighting factor (l/imp);
— values of volume flow, volume, temperature, excess pressure in the form of a digital coded signal;
— display on the display of the measured values of volume flow, volume, temperature, overpressure (for version with display);
- RS-485 serial interface, which allows to connect flowmeters into a network via a half-duplex multipoint differential communication line of the "common bus" type in order to transmit information about the results of measurements of volumetric flow, volume, temperature, overpressure using a digital (discrete) coded signal;
— serial interface RS-232С, which is used by the manufacturer for technological purposes;
- frequency-pulse outputs - passive circuits, which are optocouplers with transistor switches at the output.

General recommendations for the placement, installation and operation of electromagnetic and other flow meters (water meters)
Flowmeters usually designed for installation in heated rooms or special pavilions with a positive ambient temperature Toc (air) usually from 0 to +50C and relative humidity not more than 80%. The instruments must be freely accessible for inspection at any time of the year. The place of installation must guarantee the operation of the device without possible mechanical damage. Installation of water meters in flooded, cold rooms at temperatures below 5C, and in rooms with humidity over 80% is not recommended (except for special versions: for negative temperatures or "flooded" version for flow converters with dust and water protection code IP68).
When installing an electromagnetic flow meter, the following mandatory conditions must be met:
b) Installation is carried out in such a way that the device is always filled with water(installation in a pressure pipeline);
c) Requirements for straight sections for an electromagnetic flowmeter:
When installing the device after bends, shutoff valves, adapters, filters and other devices that create flow distortion, it is necessary to provide for a straight section of pipelines for straightening the flow from 2 to 5DN long(depending on the type of hydraulic resistance preceding it - see the figure (confuser, valve, outlet, filter, sump, valve, pump, etc.)), and behind the device - at least 2Du (where Du is the conditional diameter of the pipeline). It should be taken into account that if the installation conditions are violated, an additional measurement error appears.
d) In case of repair or replacement of the water flow meter before the direct section upstream of the device and after the direct section of the pipeline after the device shut-off valves (faucets, valves, gate valves, valves) are installed, as well as drains / drains for emptying the disconnected section, which are mounted outside the area of \u200b\u200bstraight sections.
e) Before the device, but after the shut-off valves outside the area of the straight section of the pipeline; as well as after the meter when installing it on the return pipeline of the hot water supply or heating system (heat supply), to the shutoff valves it is recommended to install water filters(straight or oblique coarse mesh filters).
f) It is not allowed to install an electromagnetic flow meter at a distance of less than 2 meters from devices that create a powerful electromagnetic field around them (for example, power transformers and cables), as well as placing the device in the area of permanent magnets or getting the pipeline under voltage.
