Upper And Lower Limit Alarm Liquid Flow Measurement NYLD-CR Insertion Type Electromagnetic Flowmeter
NYLD-CR Insertion Type Electromagnetic Flowmeter Working Principle
NYLL-CR insertion type electromagnetic flowmeter is a new type of flow meter developed on the basis of pipeline type electromagnetic flowmeter, which retains the advantages of pipeline type electromagnetic flowmeter on the basis of pipeline type electromagnetic flowmeter in the pipeline installation difficulties, large costs and other defects, according to the NIKURADS (NIKURADS) principle, electromagnetic method by measuring the average flow rate of fluid, so as to obtain the fluid The volume flow rate. Especially after the use of open hole with pressure, with pressure installation technology, insertion type electromagnetic flowmeter can be installed in the case of non-stop water, but also in the cast iron pipeline, cement pipeline installation. The successful development of insertion electromagnetic flowmeter, for the fluid flow detection provides a new means.

NYLD-CR Insertion Type Electromagnetic Flowmeter Design Feature
1. In the pipeline flow detection, simple installation, can not stop the flow, the site can be opened with pressure, with absolute installation advantages and price advantages.
2. Suitable for water, sewage, acid, strong alkali and other conductivity in 20cm or more liquid flow detection, changes in conductivity does not affect the change in performance, extremely strong to adapt to complex changes in fluid, especially for the supply and drainage pipeline flow measurement.
3. Flowmeter mechanical movable parts, converter using optimized design, tight structure, easy to install, converter and sensor with interchangeability, free to change the detection range of measured flow (0.5m / s ~ 10m / s).
4. It is only related to the insertion depth, so it has wide versatility and interchangeability. One model can be applied to the fluid measurement requirements of various sizes of pipes. Automatic range switching function. Flow meter in the flow range changes, the range can be automatically switched to ensure accurate measurement within the full range.
5. Forward and reverse flow calculation function. The user can choose positive metering or reverse metering (factory is positive metering).
6. Upper and lower limit alarm, empty tube alarm.
7. Power failure protection, parameters will not be lost after power failure, EEPROM can save the set parameters and accumulated values.
Small signal removal function. Users can set the lower voltage or lower flow rate through the display panel to cut out the small signal of interference.
8. The instrument applies the principle of "auto-zeroing" to eliminate electrochemical interference signals, and the zero point is self-stabilizing.
9. The converter and sensor have various protection levels and installation methods, including IP68 for submersible installation.
