流量计与质量流量控制器

最高质量的流量计

美国斯亚乐仪表有限公司为几乎所有的气体、液体与蒸汽生产高性能的质量流量计与质量流量控制器。 SIERRA 满足客户在高精度、高重复性的流量测量，快速的生产交货，专家的咨询，长期的支持等多方面需要。我们向全球众多的客户提供创新的、高质量的产品与服务，帮助他们显著地降低生产成本、提高效益。需要解决问题——客户会选择 SIERRA。

我们拥有出众的产品质量与遍布全球的流量专家，始终如一地将最高的流量测量解决方案带给我们的客户。

体验我们对流量的激情！

我们的热式质量、时差型超声波，涡街与多变量仪表是标准化产品，又可为客户在实验室、工业与危险环境的应用情况而特别订制。 SIERRA 的流量测量技术能够测量与控制非常低的气体流量（小至满量程为每分钟1标准毫升）到气体、液体与蒸汽的特大流量。我们有粗糙表面的设计、切边技术的创新和由全球47个国家的107个办事处所组成的流量专家队伍，这就是全球的客户信任 SIERRA 的原因。

您有怎样的流量测量需求？

我们将向您提供经济效益的、健壮的、严谨的解决方案：
气体 * 空气监测 * 尾气排放 * 氧气 * 水 * 柴油机 * 排水 * 微粒 * 分析测量等等　　

我们所提供的产品与服务：

质量流量计与质量流量控制器
- 我们是顶级质量、性能的质量流量测量与控制仪表的制造商。我们提供气体、蒸汽、水及其他液体的流量仪表。
基准式流量标定与现场服务
- 我们的质量流量计与控制器有专业的可溯源NIST的基准式标定、维修与现场服务。
OEM、定制及客户解决方案
- 我们提供ＯＥＭ（Original Equipment Manufacturers）的解决方案，或满足客户特别价格与应用要求的设计与制造。
Sierra 尾气测量系统
- 我们生产著名的ＢＧ－３型瞬时颗粒流量分析系统，用于引擎研发与检定时排放气体的颗粒采样。我们还提供其它的引擎尾气系统的工具、附件、测试自动化解决方案与顾问服务。

提供投资的高回报

直接式的质量流量测量与标定大大提高了精度、降低了成本。
直接式的质量流量不需要温度／压力补偿装置与流量计算机。
对过程温度与压力的变化有免疫力，具有非常好的重复性。
对于气体，密度是高度变化的。气体的体积流量对温度、压力的变化极为敏感。
超过 80% 的工业过程——例如化学反应、燃烧、氧化、通风等，都是基于质量流量，而非体积流量。

业届领先的客户服务

Sierra 仪表有限公司注重提供高质量的服务与支持，注重我们与客户的良好关系。作为30多年的工业企业，Sierra 与每一个客户都保持着一对一的良好沟通。欢迎您随时与 Sierra 联系。

Flow Meters - Mass Flow Controllers

The Highest Quality Flow Meters Available

Sierra Instruments manufacturers high performance mass flow meters and mass flow controllers for nearly any gas, liquid, or steam application. Customers choose Sierra when they need an accurate and repeatable flow measurement, short delivery lead times, expert flow advice, and long term support. We provide innovative, high quality flow meters and services to top businesses around the globe, helping them to achieve significant cost savings through increased efficiencies. When it matters, customers choose Sierra.

By combining superior quality in our flow meters with a talented global network of flow meter experts, we consistently deliver the best flow measurement solutions to our customers.

Experience Our Passion for Flow!

Our Thermal Mass, Transit-Time Ultrasonic, Vortex Shedding and Multivariable flow meters are available in both standard and customized versions for applications in laboratory, industrial, and hazardous environments. Sierra's flow measurement technologies precisely measure or control very low flows down to less than 1 sccm full scale as well as extremely high flows of gas, liquid, and steam. With rugged product design, cutting-edge innovation, and a team of flow experts Sierra Instruments comprises 107 offices worldwide in 47 countries. Experience why customers around the globe rely on Sierra.

What Are Your Flow Measurement Needs?

We provide cost effective, robust, turnkey flow meter solutions for:

Gas
Air Monitoring
Emissions
Oxygen
Water
Diesel
Displacement
Particulate
Analyzer Measurement

The suite of flow meters and services we offer:

Mass Flow Meters & Mass Flow Controllers - We are a manufacturer of premium quality & performance Mass Flow Meters and Mass Flow Controllers. We provide natural gas flow meters, mass air flow meters, water flow meters, and oxygen flow meters. Sierra also carries pipe flow meters, ultrasonic flow meters, digital flow meters, and several other meters to measure liquids and steam.
Primary Standard Flow Meter Calibration & Field Services - We specialize in Primary Standard NIST traceable calibration, repair, and field services for mass flow meters and mass flow controllers.
OEM, Private Labeling & Custom Solutions - We provide flow meter solutions for Original Equipment Manufacturers (OEM), Private Label, and general customers to meet their pricing and design goals.
Sierra Emissions Systems - We manufacture the well-known Model BG-3 Transient Partial Flow Dilution System used to sample engine exhaust particulate emissions during engine R&D and Certification. We also supply other engine emissions systems tools, accessories, test cell automation solutions, and consulting services.

Providing a High Return on Investment

Direct mass flow meters provide improved accuracy and cost efficiencies.
Direct mass flow meters do not need pressure or temperature compensation equipment or flow computers.
Flow meters provide immunity to process changes in P & T, leading to very repeatable measurements.
In Gases, density is highly variable. Unlike mass flow meters, volumetric gas flow meters are very sensitive to changes in pressure and temperature.
Mass flow meters are a necessity in over 80% of all industrial processes such as those involving chemical reactions, combustion, respiration, and HVAC, which are based on mass flow, not volumetric flow.

Industry Leading Customer Service

Providing quality service and support is very important to Sierra Instruments and we value the relationship we have with our customers. In fact, when you call Sierra, you talk to a live person, all the time, every time. With 30 years in the mass flow meter industry, Sierra Instruments takes pride in offering a one-on-one approach with each valued customer.
