Insertion-type electromagnetic flowmeter
The plug-in electromagnetic flowmeter is a new type of flow instrument developed on the basis of the pipeline electromagnetic flowmeter. While retaining the advantages of pipeline electromagnetic flowmeters and addressing their drawbacks such as difficult installation and high cost, it uses an electromagnetic method to measure the average flow rate of the fluid, thereby obtaining the volumetric flow rate of the fluid. Especially after adopting pressure drilling and pressure installation technology, the plug-in electromagnetic flowmeter can be installed without stopping water, and can also be installed on cast iron pipes and cement pipes. The successful development of the plug-in electromagnetic flowmeter provides a new means for fluid flow detection.

Product Description
Main Features
■ Insertion electromagnetic flow meter, easy installation, continuous flow, on-site pressure opening is possible.
■ Suitable for water, sewage, acid, strong alkali and other conductive liquid flow monitoring. Changes in conductivity do not affect performance. Especially suitable for flow measurement in drainage pipes.
■ The flow meter has no mechanical moving parts. The converter adopts an optimized design, with a compact structure and easy installation. The converter and sensor are interchangeable, and the measuring range (0.5m/s~10m/s) can be freely changed.
■ The detection of flow rate is only related to the insertion depth, so this flow meter has wide versatility and strong interchangeability. One model can be used for fluid measurement requirements in various specifications of pipelines. It can be connected to any standard secondary instrument.
(a) 4~20mA
(b) Pulse output can be set
(c) RS485 interface, HART communication protocol, MODBUS protocol.
■ Automatic range switching function. When the flow rate changes within the flow range, the range can be automatically switched to ensure accurate measurement within the full range.
■ Forward and reverse flow meter function. Users can choose forward flow meter or reverse flow meter (forward flow meter ex-factory).
■ Upper and lower limit alarm. Users can set the upper and lower limit instantaneous flow rate as needed. When the flow rate exceeds the upper or lower limit set value, the buzzer will alarm or there will be relay output (optional for users).
■ Empty pipe alarm. In the working state, when the flow level measuring pipe is empty, the instantaneous flow rate is zero, and an alarm is displayed in the upper right corner.
■ Power-off protection. The calculation results and user-set parameters of the flow meter will not be lost after power-off. EEPROM can save the set parameters and cumulative values.
■ Small signal elimination function. Users can set the lower limit power through the display panel to eliminate interference small signals.
■ The instrument uses the "automatic zeroing" principle to eliminate electrochemical interference signals and stabilize the zero point.
■ The converter and sensor have various protection levels and installation methods, and there is IP68 suitable for underwater installation.
