How to choose the most practical speedometer based on the actual situation, the following are some suggestions given by YC speedometer manufacturer professionals:
First, determine the measurement medium, look at the degree of corrosion of the measurement medium, and select the corresponding transmitter according to the degree of corrosion. Generally speaking, the transmitter with stainless steel as the isolation unit can be used for non-strong acid and strong alkali, otherwise, you can only choose special Special transmitters such as titanium alloy designed for corrosion protection.
Secondly, it depends on whether the measuring medium is viscous and clean. If it is very viscous (for example, the flow is very slow), you need to choose a transmitter with a rigid isolation unit. Determine the measurement range and measurement method. Generally, when selecting the measurement range, the actual measurement range and the overvoltage measurement range should be considered. The selection range is subject to the maximum measurement range, and the size of the overvoltage measurement range is considered.
In addition, you need to choose the correct measurement method. If you need to measure the differential pressure, you must choose a differential pressure transmitter to determine the accuracy range and compensate for the temperature range. The use temperature range is based on the lowest accuracy you need to measure. Generally, select a difference slightly higher than the required minimum accuracy of Pressure transmitter products.
At the same time, long-term stability indicators need to be considered when selecting a speedometer. The so-called compensation temperature range is the temperature range of the Water level electrode during normal operation. The use temperature range is the maximum temperature range that may occur during use. Generally, the temperature range is slightly larger than the required temperature range.
