Filtering extra pulses from water meter

ESPHome
1

I’m using a DAE AS250U-100P water meter (one pulse per 10 gallons) in line with a servo valve relay, attached to the same ESP8266. I’m having issues with extra pulses from the meter. It pulses correctly every 10 gallons (roughly every two minutes when the valve is open), but also frequently pulses one or several times when the valve is opened/closed. I have no idea what’s creating this, but it renders the rest of the data unusable. Has anyone had this issue and/or can suggest ways that I might filter out those extra pulses?

The ultimate goal is to be able to use this not only for metering, but for shutting the valve off automatically if there is ever a detectable leak.
