2. Electromagnetic flowmeter air traffic control alarm closed Does it affect the flow rate?
Turning off the electromagnetic flowmeter air traffic alarm has no effect on the flow rate. According to relevant information, there is a situation where Hu Bifan belongs to the battery powered electromagnetic flowmeter. Its excitation alarm is detected by the resistance of the excitation coil during hail detection. Although an excitation alarm may
3. Conductivity Range of Electromagnetic Flow Meter
Electromagnetic flow meters have clear requirements for liquid conductivity. The universal type can measure a minimum of 5 × 10 ⁻⁶ S/cm, while the non-contact capacitive coupling type can measure a minimum of 5 × 10 ⁻⁸ S/cm. However, low conductivity media such as petroleum products and gases cannot be measured.
. 1. Applicable range of conductivity for different models • Universal instruments: The threshold is usually in the range of 10 ⁻⁴ to 5 × 10 ⁻⁶ S/cm, and in actual use, it needs to be comprehensively judged based on parameters such as signal line length and distributed capacitance. Non contact capacitive coupling type: The electrode is not in direct contact with the liquid and can measure liquids with conductivity as low as 5 × 10 ⁻⁸ S/cm, such as partially ultrapure water or weak electrolyte solutions. Battery powered type: Usually requires a conductivity of>20 μ S/cm (i.e. 2 × 10 ⁻⁵ S/cm), suitable for outdoor or mobile scene detection of industrial water. two Typical liquid applicability example • Industrial aqueous solution: The conductivity is generally greater than 10 ⁻⁴ S/cm (such as acid-base salt solutions), and a universal instrument can be directly used. Low alcohol distilled water: with a conductivity of about 10 ⁻⁵ S/cm, it can still be measured by some high-sensitivity models. Bofang • Organic liquids: Petroleum products, ethanol, etc. typically have conductivity<10 ⁻¹⁰ S/cm and cannot trigger instrument response. three Usage restrictions and precau
