Product details
Acid and alkali flow metersIt is an electromagnetic induction flow meter, a high-tech electromechanical product that integrates signal detection and microelectronic intelligent technology. It is divided into two categories: on-site display type (integrated type) and remote display type (split type). It can measure the volume flow rate of conductive liquid media, including highly corrosive liquids such as acids, alkalis, salts, pulp, mud, wastewater, and solid-liquid two-phase suspensions. This product is widely used in industries such as petroleum, chemical, metallurgical, textile, food, papermaking, as well as in fields such as environmental protection, municipal management, water conservancy construction, and river dredging.

1. Display function

It can display cumulative flow, instantaneous flow, flow rate, communication address, and output the maximum flow corresponding to 20mA (which can be set arbitrarily) and flow direction indication.

2. Intelligent operation settings

With just four buttons on the panel and LCD screen prompts, configuration and control can be completed, and it is simple, fast, convenient, and safe.

3. Automatic range switching function

The flow meter can automatically switch its range when the fluid flow rate varies widely, ensuring accurate measurement throughout the entire range.

4. Self check fault, alarm function

When the flowmeter is in operation and there is an empty tube, excitation open circuit or short circuit inside the measuring tube, it will automatically sound an alarm. The red light is on, and the alarm content is displayed at the same time.

5. Upper and lower limit flow alarm function

Users can set the upper and lower limits of the flow rate according to their needs. When the flow rate exceeds the set value, an automatic alarm will be triggered, the red light will turn on, and the alarm content will be displayed. The user can also output a switch signal to control the actuator.

6. Signal output function

The flowmeter can output 4-20mA standard current signals and 0-11kHz pulse signals, and can be used in conjunction with supporting equipment or other control systems such as microcomputers.

7. Communication function

The flowmeter is equipped with an RS485 communication interface (9600 baud, half duplex), which can be connected to the flowmeter network using twisted pair shielded cables, or directly connected to the microcomputer through a passive signal converter in our unit using a telephone line.

8. Small signal cutoff function

Users can set the lower limit voltage and lower limit flow rate through the display panel to cut off the small signal flow caused by interference.

9. Power outage protection function

The calculation results of the flowmeter and the parameters set by the user will not disappear after power failure, and will be stored in E2PROM for a long time.

10. Electrical isolation

There is electrical isolation between all output circuits and between them and the input circuit.

11. Modular design

The signal processing adopts modular design, which is convenient for on-site maintenance and replacement, and does not require recalibration.

12. Anti interference

Low frequency ternary wave excitation is not affected by various noise disturbances such as power frequency and on-site conditions, and its stable operation relies on.

13. Low power consumption

Low power consumption dual power supply design: 220VAC or 24VDC input, power consumption ≤ 15W

14. Damping function

The range can be set from 0 to 9 (any integer in between).

15. The sensor structure is reliable

The sensor structure is reliable, with no movable parts and no throttling elements that hinder liquid flow, making it particularly suitable for measuring media such as slurry, pulp, slurry, sewage, etc. with suspended solids, solid particles, fibers, etc.

16. Diversified structure

The electrode structure of sensors is diverse, and detachable, fixed, and scraper electrodes can be selected according to different application conditions.

17. Material diversification

The sensor housing and flange are made of carbon steel or stainless steel, and there are various materials available for the electrode and lining, which have the characteristics of corrosion resistance, wear resistance, and long service life.

18. Easy installation

Easy to install, can be installed horizontally, vertically, or at any angle, with low requirements for upstream straight pipe sections.

19. General Instrument Coefficient

The instrument coefficient is not affected by fluid and characteristic parameters (density, viscosity), working conditions (pressure, temperature), and conductivity (not less than the minimum conductivity). It can be calibrated under typical media (usually water) and does not require additional correction when applied to other media.

20. Plug in acid and alkali flowmeter

The plug-in electromagnetic flowmeter can measure the volumetric flow rate of conductive liquid media with a diameter greater than 200mm. Its instrument has a small volume, light weight, and can be loaded, unloaded, cleaned, inspected, and maintained without interruption.
