With the increasing level of automation development in the chemical industry, differential pressure transmitters play an important role in automated production. The selection of differential pressure transmitters should pay attention to the following points: First of all, it is necessary to consider the field measurement range, the accuracy required for the measurement, and the measurement function to be achieved. Secondly, consider the environment in which the differential pressure transmitter will be used. Whether there are toxic and harmful gases and flammable gases in the on-site environment. Third, the nature of the medium to be measured. For example, whether it is a strong acid or alkali, whether it is viscous, whether it is easy to solidify or crystallize, whether it will gasify, etc. Fourth, changes in operating conditions. For example, several important parameters (temperature, pressure, etc.) should sometimes be taken into account at the beginning and until normal production, when the two-phase concentration and density of the medium are changed. Fifth, consider the actual properties of the container of the object to be measured. For example, whether the structure is complex, the conformity of shape and size. In addition, it is possible to affect its internal equipment accessories and inlet and outlet material nozzles. Sixth, it is necessary to consider the versatility of differential pressure transmitter selection, mainly to reduce the specifications and varieties, and save spare parts. Seventh, it is to consider the actual process situation. For example, the type of equipment of the measured object, the physical and chemical properties of the medium, the degree of cleanliness, etc. Taking tanks and tanks as examples, the volume of the tank is small, and the measurement range is not too wide; On the other hand, due to the larger volume of the tank, its measurement range will be correspondingly larger. There are many suspended solids in the medium, such as foam, etc., and it is generally advisable to choose a single-flange differential pressure transmitter. Finally, the selection of differential pressure transmitters should also consider the economy and meet the actual situation. In this regard, care should be taken not to exceed the overall investment plan. The selection of the type, material, range, explosion-proof grade of the differential pressure transmitter is closely related to the environmental conditions, application conditions, installation conditions, medium characteristics, economy, etc., and the reasonable selection of the transmitter can better ensure the service life of the differential pressure transmitter and ensure the stability of the chemical production process.
