Hayward Flow Meters & Level Sensors

Hayward Flow Meters & Level Sensors from N.H. Yates

Most hot water boilers utilize flowmeters to measure the amount of liquid, gas, or vapor that passes through a system. While some flowmeters measure flow as the amount of fluid pass through over a certain time period, others measure the totalized amount that passes through a system. In combination with level sensors, flowmeters control the levels of water and/or gas that travel throughout a system to maintain temperature levels with a large facility. At N.H. Yates, we are proud manufacturer’s representatives for Hayward Flow Meters and Level Sensors and have utilized for many successful applications over the years. Here is more information on several of Hayward’s most popular models.
