Users of a code or standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, is entirely their own responsibility.
The addition of a liquid-filled diaphragm seal to an instrument may create a detectable error in the pressure reading. Typical extension lengths are 2 in. SI Abbreviation bar bar kPa? The user shall take proper precautions so that cleanliness levels for b40.100 and pressure element are maintained after the gauge is removed from its package for installation.
1017 Pressure Gauge
General requirements are provided in section 3. American Standard taper pipe threads.
This effect will be greater on a system in which the instrument is connected to a diaphragm seal by a length of capillary. A gauge designed to indicate the pressure of corrosive or high viscosity fluids, or both.

The date of the last test may be noted on the front of the gauge. The tip of the pointer shall pass within one minor graduation line width b401.00 the inner end of the minor graduations. The pointer may overlap the graduations. After filling both the seal [para. These seals provide a basic 2 in.
The following is a list of negative gauge pressure. Normal mounting of the gauge shall not prevent proper function of the case pressure relief means. This seal is suitable for rapidly flowing process fluids.
Pressure Test Gauge ASME B
A coating on the diaphragm or housing may function as the gasket. B-4 Referenced Documents The edition bearing the latest date of issuance shall be used. Customary units are used primarily in English-speaking countries and are b4.0100 replaced in most countries by SI units. The dial size and case design is designated by one of the following symbols: The O-ring v40.100 connection see Figs.
The EN includes mandatory dimensions, metrology, and testing requirement for sale in the European Union. Gauges contaminated with hydrocarbon pressure media shall not be used on oxygen regulators. It may be expressed as a pressure or as a percentage of full scale. When valves are positioned as shown in Fig.

Consult the manufacturer or supplier for advice whenever there is uncertainty about the safe application of a pressure gauge. Several methods may be employed to fasten awme upper, mid, and lower housing together. This type of seal consists of an elastomeric 4b0.100 installed within the connection of a pressure instrument or within an adapter fitting see Fig. The fill fluid is automatically degassed during the fill operation. This Standard b40.1000 not include gauges of special configuration designed for specific applications, edge reading, deadweight or piston gages, or any other gauges not using an elastic element to sense pressure.
In operation, the system to be filled is attached to the fill station. Corrosion of the pressure element assembly in the first installation may be sufficient to cause early failure in the second installation. This error is caused by internal case pressure changes and depends on fill media, extent of fill, and other factors. The housing diameter corresponds to the size of the sealing face of a standard flange or standard clamp connection. If gauge cleanliness is important for the application, such as for use on equipment involving food processing, life support, or oxidizing fluids, the user should specify the appropriate level of cleanliness listed in Table 2.
Red Flag This Post Please let us know here why this post is inappropriate. Caution must be 56 2. C-2 and C-3 shall be supplied unless otherwise specified and shall include the threaded end, union nut, tail piece, and O-ring.
All pressure gauges shall be subjected to nine blows. Caisson gauges are intended for use in submarine escape trunks and decompression chambers. Conduct the accuracy test within 10 minutes. Flanged seals are generally limited to the maximum rating of the flange itself. Some of these are a piston gage hydraulic or air b manometer c test gauge d pressure transducer or transmitter Selection of a standard is determined by the accuracy and pressure range of the gauge being tested, suitability of the medium, convenience of use, and availability.
A resonance may occur in an internal part of the gauge, with no outward manifestation. Because of this difference, gauges made to the inchbased sizes may not be interchangeable with those made to the EN sizes, even though the nominal sizes may be very close.
It is generally accepted that there is no known means of predicting the magnitude or effects of this type of failure. A corrosive medium may dictate use of an element material having less than optimum properties.
It is usually expressed as a percentage of span. This listing is intended as an outline only with paragraph references to detailed descriptions. For gauges used to measure gas pressures of psi 2 kPa and higher and liquid pressures of 1, psi 7 kPa and higher, cases with pressure relief means are recommended. An instrument may be filled by attaching it to a manifold and applying vacuum to the connection until all air is removed.
The purpose of this construction is to exclude ambient corrosives or asmme the internals from damage caused by severe vibration or pulsation.
