Insertion Electromagnetic Flowmeter

Insertion electromagnetic flowmeter has absolute installation and price advantages in pipeline flow detection,as it can be easily installed and used for continuous flow detection. 

Applicable to water,sewage or liquids with conductivity ≥ 50μs/cm,the conductivity changes will not affect the product performance. It has strong adaptability to complex changes in the fluid,especially suitable for supply and drainage pipeline flow measurement. 

Movable mechanical parts and converter has optimized design and compact structure,easy to install. Converter and sensor are interchangeable and measuring range can be freely changed (0.5m/s~10m/s). 

 The flow detection is only related to the insertion depth,so the flowmeter has wide versatility and strong interchangeability.It can be applied to a variety of pipeline specifications and can be connected with any standard secondary meter. (A)4~20mA (B)Impulse (C)Modbus RS485,HART 

Automatic range switching:The range can be automatically switched to ensure that the full range of accurate measurement when flow changes. 

Positive and negative flow direction calculation:Users can choose positive measurement or reverse measurement (factory setting:positive). 

Upper and lower limit alarm:Users can set the upper and lower instantaneous flow limit,when the flow exceeds the upper limit or lower limit set value,buzzer will alarm or set relay output (user selectable) 

Empty pipe alarm:Under working condition,when measuring the empty pipe,the instantaneous flow rate is zero and the left center of the screen will show false alarm. 

Power‑off protection:The flowmeter operation results and set parameters will not be lost when the power is turned off, EEPROM can save the set parameters and cumulative value. 

Small signal removal:Users can set the lower limit voltage or lower limit flow rate through the display panel, so as to remove the small signal interference. 

The instrument has "automatic zeroing" function to eliminate electro‑chemical interference signals, and the zero point is self‑stabilizing. 

The sensor has a variety of protection levels and installation methods,including IP68 for submersible installation.
