MNF-01 Flow Switch is an intelligent thermal diffusion principlebased flow monitoring sensor. It adopts ARM processing core and combines with high quality sensors and dedicated circuit. With temperature-compensation and calibration, it can ensure measurement accuracy in the case of water temperature change. It is available for real-time monitoring of pipe water flow. It can be used for cooling or lubrication system flow monitoring to realize pre-warning and protection for critical equipment when there is flow fault. It uses fully enclosed design, stainless steel construction to adapt to a variety of application environment. It is with overvoltage, over-current and reverse polarity protection function. MNF-01 supports quick action point set that enables installation in any direction, and noneed for frequent adjustment and maintenance. It can be applied for operation protection of large equipment in fields such as power generation, metallurgy, steel, paper, boilers etc.

Ordering Notes:
1. Please fully understand the medium conditions, pressure range, etc. Avoid unnecessary losses caused by unreasonable use of products.
2. Although the product is designed with various protection measures, for extreme applications, such as strong lightning on site, the power supply should be reliably grounded and a lightning protection device should be installed to reduce the probability of product failure as much as possible.
3. For special application, our company can provide specially designed products, and customers are welcome to consult and negotiate. Sales support: sales@manoinstrument.com we will provide you with a full range of services.
