Mass Flow Terminal

The Texas Commission on Environmental Quality (TCEQ) Air Monitoring Division is soliciting bids for the procurement of one Mass Flow Terminal, specifically a Molbox2-A700K model manufactured by Fluke Electronics (Part #6074904) or an equal alternative, under Request for Bid 582-26-15424. The equipment serves as a primary flow standard for the TCEQ Calibration Laboratory to calibrate and verify secondary equipment in air monitoring networks. The mass flow terminal must be new and of current production, featuring manufacturer's standard parts and accessories along with comprehensive hardcopy and digital manuals containing operating instructions, circuit descriptions, maintenance procedures, and safety information. Technical specifications are stringent, requiring compatibility with TCEQ's existing molbloc-L laminar flow elements, power specifications of 85-264 V ac at 47-440 Hz with maximum 18 VA consumption, operating temperatures between 15°C and 30°C, and pressure/temperature sensors with defined measurement uncertainties including absolute pressure measurement uncertainty of 0.01 percent of reading or 0.003 percent of span and temperature measurement range of 0 to 40°C with 0.01°C resolution. Flow measurement must cover 0 to 100 percent of existing molbloc-L laminar flow elements with a range of 50 sccm to 30 slpm, with resolution of 0.0015 percent full-scale and precision of 0.07 percent of reading. A minimum one-year warranty covering complete system, parts, and labor is required from the date of acceptance. Prospective bidders must submit questions regarding specifications by March 24, 2026, at 12:00 PM CST, with sealed bids due March 31, 2026, at 2:00 PM CST at the TCEQ facility located at 12100 Park 35 Circle, Building B, Austin, TX 78753.
