Product description:

I. Overview
JC-LDC plug-in electromagnetic flowmeter is developed on the basis of pipeline on a new type of electromagnetic flowmeter flow meter, basic piping it to retain the advantages of the electromagnetic flowmeters, electromagnetic flowmeters for pipeline installation in the pipeline difficult, costly defects, according to M.Niculae magnetic principle, electromagnetically by measuring the average flow velocity of the fluid so as to obtain the solution of fluid flow problems, especially the use of hot tapping, with pressure after mounting technology, making the insertion electromagnetic flow meter of water can be kept in case of installation, can also be installed on cast iron pipes, cement pipes, the successful development of plug-in electromagnetic flowmeter for detecting fluid flow provides a new tool.
Second, product characteristics

  • Plug-in electromagnetic flowmeter in pipeline flow detection, installation is simple, do not stop, field-Tapping, installation has the absolute advantage and price advantage.
  • For water, sewage, acid, alkali and other electrical conductivity in 5us / cm or more liquid flow detection, the change does not affect the change in the electrical conductivity properties of highly complex changes to adapt to fluid especially suitable for flow measurement of water pipes.
  • Flowmeter no mechanical moving parts; converter optimized design; compact structure; easy to install; converters and sensors are interchangeable; can be changed freely measurement range (0.5m / s ~ 10m / s).
  • The detected flow only to the depth of insertion, so that meter wide versatility, interchangeability strong. A model can be applied to a variety of fluid measurement requirements pipes can be connected to any standard secondary instrument.

(A) 4 ~ 20mA current output;
(B) can be set to pulse output;
(C) RS485 interfaces, HART communication protocol, MODBUS protocol.

  • Automatic range switching function at the flow meter range, the range can be switched automatically to ensure accurate measurement of full scale.
  • Reverse flow calculation function. Users can select forward or reverse metering metering (default is forward measurement).
  • Upper and lower alarm. Users can set upper and lower limits as required instantaneous flow when the flow exceeds the upper or lower limit value alarm buzzer or relay output (user selectable).
  • ATC alarm in working condition, when the inner tube air flow meter pipe, the instantaneous flow rate is zero, the upper right corner to display the alarm.
  • Power protection, the parameters set by the user operation results and the meter will not be lost after a power failure, EEPROM set parameters can be saved and accumulated value.
  • Low-cut function. Users can set the display panel or the lower voltage limit traffic, thus cut small signal interference.
  • Instrument 'auto-zero' principle, the elimination of electrochemical interference signal, zero self-stabilizing.
  • Converters and sensors with a variety of protection rating and installation, there are IP68 suitable for diving installation.
