FAQs (Frequently Asked Questions)
When employing the small electromagnetic flow sensor for chemical liquid VNS to measure pulsation flow of a "direct drive diaphragm pump", is "pulsation flow measurement mode" suitable to measure the flow?
"Pulsation flow measurement mode" is the mode specifically purposed for electromagnetic-type (solenoid-type) diaphragm pumps. In the case of motor-driven pumps such as direct drive type, "constant flow measurement mode" is suitable (The flow-rates shall be within the constant flow measurement mode's flow-rate range). When considering use of VNS, please contact us after confirming the pump's manufacturer and the model.
