At present, the input impedance of the electromagnetic flowmeter conversion path has been greatly improved, the electrical conductivity of liquid does not usually cause errors due to the change of conductivity of medium, but for the converter input impedance, the electrical conductivity of measured medium has a lower limit min, they should not be below the lower limit value.

The electrical conductivity of measured medium is too big is not allowed.
For example, when more than 10 - conductivity
1 (
S/cm)

, can reduce traffic signals, to change the indicated value, the instructions flow value less than the actual flow.

This is because in the electromagnetic flow meter, the magnetic field of finite length, measured the conductive liquid, only through the limited magnetic field to produce induced electromotive force e.

So, on behalf of the traffic signal induced electromotive force e is the result of the magnetic field department of conductive liquid cutting lines of magnetic force, magnetic field on both ends of the outside of the conductive liquid without any contribution of e.

Instead, because they are two electrodes are connected, it is a department of the open circuit.

When transmitter and converter connected together, the department of external circuit in parallel with the converter input impedance and become a transmitter of the load, when the electrical conductivity of measured medium is very big, the resistance/small, up to no matter how high input impedance converter, when the liquid external shunt results will depend on the department, which reduce the accuracy of transfer between the transmitter and transducer.

So, for an electromagnetic flowmeter, open channel flow meter is not influenced by medium conductivity have certain scope, conductance measured medium series of neither too big nor too small.

With the development of electronic technology, the progress of the converter input impedance, will can reduce the lower limit of the conductivity measured medium coupling agent affect measurement accuracy.

To guarantee and good contact with pipes, installing a transducer needs pipe surface uniform coating a layer of coupling agent, the general thickness of (
2mm-
3mm)
。

The bubbles within the coupling agent and granule, the launch of the transducer surface closely on the pipe wall.

Measurement of the circulating water flow meter is installed in the water well, environment humidity, sometimes under water, if choose average coupling agent, in a short period of time will be failure, affect measurement accuracy.

Therefore, you must choose a special waterproof coupling agent, coupling agent should be used within the period of validity, generally for 18 months.

To ensure measurement accuracy, every 18 months should replace the transducer, and replace the coupling agent.
At a time when technology is essential for mass flow meter, ensuring that it works in a symbiotic way with your human employees is key.

Abstract: the power meter scale in the application of oxygen measurement information produced by excellent flow meter, flow meter manufacturer to offer you the quotation.

In the process of industrial raw main oxygen, oxygen pipeline must be equipped with corresponding flow measurement system.

Due to economic accounting and fees, the measuring accuracy of the oxygen flow increasingly aroused people's concern.

Most previous orifice plate is used to measure oxygen flow,.

More flow meter manufacturers choose model price quote you are welcome to inquire, here is the power meter scale in oxygen measurement, the application of article details.

In the process of industrial raw main oxygen, oxygen pipeline must be equipped with corresponding flow measurement system.

Due to economic accounting and fees, the measuring accuracy of the oxygen flow increasingly aroused people's concern.

Most previous orifice plate is used to measure oxygen flow rate, and selection of appropriate intelligent flow meter automatic compensation correction due to oxygen pressure and temperature changes caused by the error, in order to improve the measuring accuracy.

Orifice plate has simple structure, wide adaptability and the fluid is standardized, but in practice, sometimes it is difficult to estimate error, the key lies in the test section at a time.

It is well known that traditional orifice throttling device is difficult to overcome shortcomings: range ratio is too small, usually only 3:1, makes the big flow can't juggle, small flow rate measurement, often causing traffic cumulative values produce large error;

Second, the pressure loss of the orifice throttling device is bigger, is not conducive to energy conservation, and construction is big, the high cost of installation.

Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.

The coriolis density meter mass flow meter is also available as a fork density meter manufacturer.
Although there are various available in the market (such as tuning fork liquid density meter, electromagnetic flow meter slurry, and low flow turbine flow meter), recent study results have made this u shape coriolis mass flow meter mass flow meter a preferred mass flow meter choice of the people.
The endress hauser ultrasonic flow meter mass flow meter has significantly numerous benefits over other endress hauser coriolis mass flow meter systems, which makes it first choice for insertion ultrasonic flow meter.

Where to avoid installing the mass flowmeter 1. Places with large temperature fluctuations Since the large fluctuations in temperature will change the volume of the fluid, so when installing the mass flowmeter, avoid installing it in places with large temperature repetitions Moreover, the temperature of the installation environment should ensure that the fluid in the measuring tube can feel comfortable, and avoid large temperature fluctuations, so as not to affect the measurement accuracy due to changes in the volume of the fluid in the measuring tube. 2. Where there is radiant heat Radiant heat will also cause errors in the measurement of the mass flowmeter, and it will also damage some of the precision parts. Therefore, the place where the mass flowmeter is installed should avoid radiant heat. However, some production places will inevitably have radiant heat, so good radiant heat isolation measures must be taken to reduce the impact of radiant heat on the flowmeter. 3. Corrosive places Corrosive gas will cause serious damage to the precision parts in the mass flowmeter, and the gas permeability is very strong, so even if some protective measures are taken, it is difficult to Completely avoid the infiltration of corrosive gas into the flowmeter, so try to avoid installing the mass flowmeter in a place with corrosive gas to avoid corrosive damage.
Everyone who has a digital fork density meter wants it to look coriolis mass flow meter emerson. However, in order to achieve that, it normally involves investing in a u shape coriolis mass flow meter mass flow meter. Beijing Sincerity Automatic Equipment Co., Ltd can offer you the best solution.
