Electromagnetic flowmeter features
Using intelligent judgment, the measurement correction setting is not used, and the air traffic control alarm and electrode detection application are more convenient;
Advanced "rough error handling" technology, which can remove fluids such as slurry to measure sharp disturbances, reduce output runout, maintain high precision measurement and make output more stable;
With a fluid density setting, it can display mass flow;
Constant current excitation current range, 125mA, 250mA optional, can be used with different manufacturers, different types of electromagnetic flow sensors;
Control function with remote reset of the totalizer, with contact signal input for starting and stopping accumulation, suitable for total inspection and batch processing applications;
With self-test and self-diagnosis function;
Advanced non-volatile memory for higher circuit reliability and effective protection of setup and measurement parameters;
The meter can be equipped with an unpowered clock and memory for recording the power down time, power-on time and power-down time;
The meter has an optional hour recording function that can store flow and electrode resistance measurements for more than 30 days.
The new keyboard processing method avoids the keyboard operation affecting the measurement, and can enter and return the operation menu to make the parameter setting more convenient;
The total display uses 10-bit decimal 9999999999 full-value carry, which solves the practice of double-word full value 4294967285 (hexadecimal FFFF) carry-in habit;
With wireless transmission, the mesh network is organized by the wireless HART protocol.
Product advantage and preservation
The vortex flowmeter adopts micro-power high-tech, and can be operated continuously by lithium battery for more than one year, which saves the purchase and installation cost of cables and display instruments, and can display instantaneous flow and accumulated flow on the spot. The temperature-compensated integrated vortex flowmeter also has a temperature sensor that directly measures the temperature of the saturated steam and calculates the pressure to show the mass flow of the saturated steam. The temperature and pressure compensation integrated type has a temperature and pressure sensor. The gas flow measurement can directly measure the temperature and pressure of the gas medium, thereby indicating the volumetric volume flow of the gas.
In order to prevent accidental damage to the instrument, please keep the packaging status of our company when it is shipped to the user.
After the instrument arrives, it should be installed in time to avoid the insulation performance of the flow converter being reduced due to unexpected factors, and the metal parts are corroded. If you need to store for a long time, please observe the following:
1. When storing, try not to unpack.
2. The storage location should have the following conditions:
3. With rainproof and waterproof facilities
4. Not susceptible to mechanical vibration or shock
5. The instrument should be stored in the temperature and humidity ranges listed in the table below. The ideal temperature and humidity is 25 ° C, 65%
6. Ambient temperature -20 ° C ~ +60 ° C
7. Relative humidity 5% to 90%
The flowmeter weighing impulse flowmeter that measures the flow using the impulse theorem is used to measure the flow rate of the granular solid medium, and is also used to measure the flow rate of the mud, the crystalline liquid, and the abrasive. Flow measurement ranges from a few kilograms per hour to nearly 10,000 tons. The typical instrument is a horizontal force-separated impulse flowmeter. The measurement principle is that when the measured medium falls freely from a certain height h to a detection plate with a tilt angle, an impulse is generated, and the horizontal force component of the impulse is proportional to the mass flow rate. Measuring this horizontal component can reflect the mass flow.
The electromagnetic flowmeter is made by applying the electric conductor to generate an induced electromotive force in a magnetic field, and the induced electromotive force is proportional to the flow rate, and is measured by measuring the electromotive force to reflect the flow of the pipeline. Its measurement accuracy and sensitivity are high. Industrially used to measure the flow of water, slurry and other media. The maximum diameter can be measured up to 2m, and the pressure loss is extremely small. However, media with low conductivity, such as gas and steam, cannot be used.
The electromagnetic flowmeter has a high cost, and the signal is susceptible to external magnetic field interference, which affects the wide application in industrial tube flow measurement. To this end, the product is constantly improving and updating, to the development of computer.
