What is the Difference in Mechanical and Steam Stops?

by User Not Found | Jul 19, 2018

There are many different types of devices that can be used to measure water, air and gas. One type is called a flow meter. Flow meters operate by sensing the force of the substance when it hits a target placed in the flow stream of the chamber of a strain gage. When force is applied to the target in the flow stream, a transmitter then converts the force to a 4-20 mA output that is proportional to the flow rate.

Flow meters come in all shapes and sizes from large and robust to small meek. Many industrial applications demand equipment that can withstand hazardous environments and everyday wear and tear. Niagara Meters designed a large offering of flow meters to meet the needs of most any industrial application. The Niagara Forcemeter is a liquid, steam or gas flow meter and operates by industry tried and trusted mechanisms.

Every Forcemeter™ incorporates a mechanical stop that protects the meter from flows greater than an application’s given full-scale flow rate. Mechanical stops protect the meter in both the forward and reverse direction from being bent or damaged from excessive force. The meter will not continue to produce an output beyond the point at which a mechanical stop is set. Typically, the mechanical stop is set approximately 25% above the maximum rated full-scale flow rate per the application requirements. Mechanical stops are not to be confused with an additional protection option known as “steam” stops.

Some applications require additional protection beyond the mechanical stop due to the nature of the application. Even though the name implies the use in steam applications alone, there are also other applications where a “steam” stop could be used. Steam stops are provided for all applications where the target rod length reaches 2” and greater for both steam and non-steam applications where the rod will be subject to extreme force. It is always important to fill out the application data form so that the factory can determine the appropriate protection for the meter.

Finding the flow meter that fits your application’s demands is easy with Niagara Meters. All of Niagara’s products are built to withstand extreme environments and the toughest of industrial applications. They have been known for their robust and proven flow meter designs for over 150 years. With years of experience and a range of flow measurement products, Niagara can find the right solution for you.
