KM-5 heat meters are designed to measure and account for thermal energy, volumetric and mass flow, volume, mass and parameters of the coolant in open, closed and dead-end water heating systems (hereinafter, respectively, OVST, ZVST and TVST), as well as in circulation and dead-end hot water systems. and cold water supply (hereinafter referred to as hot water and cold water, respectively).

Scope of the KM 5 meter: commercial and technological accounting, dispatching, technological and technical control at sources of thermal energy and at consumers for pipelines with an internal diameter of not more than 300 mm.

Heat meter KM 5

KM 5 electromagnetic heat meters calculate thermal power and thermal energy based on data on volumetric flow and volume of the heat carrier, temperatures on the direct and return pipelines, taking into account changes in the heat capacity of the heat carrier when the temperature difference at the inlet and outlet changes.

Operating principle: electromagnetic.

Flow transducer sizes: from DN=15 mm to DN=300 mm. Application area: for measuring, recording and recording the amount of heat, as well as volume, mass, volume and mass flow and other parameters of the coolant in one or more controlled systems simultaneously.

Device features:

  • Wide dynamic range of flow measurement: Gmax/Gmin=1000.
  • Short length of straight sections of pipelines (3DN-1DN).
  • Standard sizes of primary flow converters from DN=15 mm to DN=300 mm.
  • The KM-5 heat meter has an empty pipe sensor, thanks to which, in the absence of coolant in the pipeline, the current result of flow measurement is reset to zero.
  • Measurement of reverse flows in automatic mode.
  • Outdoor temperature control.
  • The software of heat meters and flowmeters has an auto-calibration procedure, which allows maintaining metrological characteristics throughout the calibration interval equal to 4 years.
  • Devices, regardless of the accuracy class, meet the requirements of the best classes: 1st according to the recommendation of the International Organization of Legal Metrology (MP75) and class C according to GOST 51649-2000. Heat meters KM-5 meet the requirements of Russian and international standards according to the norms of flow measurement error.
  • KM 5 heat meters and flow meters are equipped with RS-232, RS-485 interfaces for outputting information to a printer, modem, Personal Computer or other devices.
  • The archiving depth of average hourly parameters is 42 days, and average daily parameters - 12 months, which allows, in case of disputes between the supplier and consumer of energy resources, to have objective information about the characteristics of the heat and water supply system.

The KM-5 meter includes regular flow and (or) volume converters, thermometers (temperature sensors) and (or) their sets of approved types (Table 7) and computing devices. As part of KM-5, pressure sensors and volume converters with a pulsed output signal can also be used, the types of which are indicated in Table 7. These measuring instruments are connected to the electronic blocks of the PRE.

For measurements in OVST, ZVST, TVST, having pipelines with nominal bore no more than DN 300, seven full bore modifications are used: KM-5-1 ... KM-5-7, made on the basis of PRE. Modification KM-5-1 is intended for measurements in closed and dead-end VST at sources and consumers of thermal energy. Modification KM-5-2 is intended for closed VST at consumers.

Modifications KM-5-3 and KM-5-7 are designed for open VST at thermal energy sources. Modifications KM-5-4 and KM-5-5 are intended for open VST at consumers. Modification KM-5-6 is a universal (configurable) modification designed to measure thermal energy in both closed and open VSTs, or in two independent VSTs of various types (i.e. one VST can be open and the other closed) .

KM-5 provide display of measuring information and parameters of its state on the display of a computing device or on the display of an auxiliary component of a peripheral device - an adapter of the AP-5 periphery.

The following data is displayed on the alphanumeric display of the VU:

  • thermal energy Q, Gcal and MWh for one or two (Q, Q2) thermal systems;
  • volume V, m 3 and mass M, t of coolant in the supply and / or return (feed) pipeline;
  • volume V, m 3 , the current value of the volume flow Gv, m 3 /h in the DHW (cold water) pipeline, on which the software is installed.

Description of the electronic computing unit of the KM-5 heat meter:

The electronic unit (heat calculator) of the KM-5 heat meter is an industrial controller with resident software. EB KM-5 is structurally made in a dust and moisture-proof housing, placed directly on the primary flow converter. 1 PRE, 2 thermal converters, 1 thermal converter for measuring the ambient air temperature and up to 2 pressure sensors are connected to the EB KM. The electronic unit performs the measurement, digitization and subsequent processing of the output signals of the flow, temperature and pressure sensors of the coolant.
Calculated coolant parameters can be transferred in units of measure (t/h, kPa, °C...) to a PC or to an information network via RS-485 interface. EB KM-5 is also designed to form the supply voltage of the excitation coils of the electromagnetic flow converter, the stabilized current for the PT and the supply voltage of the pressure sensors.
On the front panel of the electronic unit there is an indicator and four control buttons (see photo above).
To organize flow metering through the second pipeline and thermal metering in open heat supply systems at the consumer and at the heat source, a modification of the electronic unit is provided, which works in conjunction with the KM EB in the primary signal converter (PPS) mode. PPP performs measurement, digitization and pre-processing flow sensor signals, up to 2 pressure sensors and 2 coolant temperature sensors. Calculated values ​​and service messages (information about errors, failures, emergency situations etc.) are transferred to the CM CU via the RS-485 interface.
In heat meters KM-5-2, KM-5-3, KM-5-4, KM-5-5 and KM-5-6, one of the electronic units is made in the PPS modification.

Maintenance of heat meter KM-5.

The heat meter does not require special maintenance.
The heat meter (TS) put into operation requires periodic inspection in order to:

  • compliance with the operating conditions of the vehicle;
  • absence of external damage to the components of the vehicle;
  • checking the reliability of electrical and mechanical connections;
  • checking the presence of seals on the components of the vehicle;
  • checking the presence of supply voltage;
  • checking the functionality of the vehicle.
The frequency of inspection depends on the operating conditions, but should not be less than once a week.

Periodically (the period depends on the temperature in the pipeline and is determined experimentally), it is necessary to check the presence of oil in the protective sleeves of thermal converters and replenish its losses from drying.

In the case of the use of TS in conditions of heat carriers with a physical and chemical composition that differs from the requirements of regulatory documents, it is necessary to periodically flush the flow part of the PRE without the use of abrasive materials.
Flushing should be carried out regularly in the service mode, avoiding metrological failure. The frequency of flushing the flow part of the PRE depends on the specific operating conditions.

To reduce the effect of ferromagnetic inclusions contained in the coolant, it is recommended to use magnetic-mechanical filters.

During the operation and maintenance of the heat meter, it is necessary to comply with the "Rules for the operation of electrical installations by the consumer" and the "Intersectoral rules for labor protection (safety rules) for the operation of electrical installations".

It is FORBIDDEN to eliminate defects in the primary converter without making sure that there is no pressure in the line.

The heat meter is subject to mandatory primary verification, as well as periodic verification at least once every three years or in the case when its readings raise doubts about the correct operation of the heat meter itself.

The verification of heat meters is carried out according to the MP 42968951-2001 method.
