The suite of flowmeters and services we offer:

  • Thermal Mass Flow Meters & Mass Flow Controllers - We are a manufacturer of premium quality & performance Mass Flowmeters and Controllers for use in semiconductor, pharmaceutical and research industries. Machine builders and systems integrators are large users and specifiers of our MFC’s.
  • Vortex Shedding Flow Meters, Thermal Mass Flowmeters Inline and Insertion Probe Type, and Transit-Time Ultrasonic Flow Meters are our core industrial flow measurement technologies. We provide natural gas, mass air flow, water flow, and oxygen flow meters for industrial applications. Sierra also carries pipe, ultrasonic, digital and other meters to measure liquids and steam.
  • Free Lifetime Technical Support Since we manufacture all the products we sell online, we offer free lifetime phone and email tech support for the life of the product.
  • Fast Delivery Times | Same Day Shipment for In-Stock Since we are the manufacturer of the products we sell online, we are continuously building to stock. We reward our team for shipping orders fast. Many times the order is shipped from our factory just hours after ordering. In stock products are processed immediately, so depending on your shipping method, you will receive your product between 2 and 7 days of submitting your order.
  • Primary Standard Flow Calibration & Field Services- We specialize in Primary Standard NIST traceable calibration, repair, and field services for mass flowmeters and 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.

Providing a High Return on Investment

  • Mass Flowmeters provide immunity to process changes in P & T, leading to very repeatable measurements.
  • Direct mass meters provide improved accuracy and cost efficiencies.
  • Direct mass meters do not need pressure or temperature compensation equipment or flow computers.
  • In Gases, density is highly variable. Unlike thermal mass meters, volumetric gas 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.
