and backpressure. Sharp-edged orifice plates often change readings over time due to wear, even with non-abrasive fluids. Venturis are great, but their cost is often prohibitive. A flow nozzle offers the best of both worlds: a low-cost solution that wears well and has relatively low pressure drop. In our design, the flow nozzle is manifold mounted to the gauge, which minimizes leak paths and reduces overall gauge size. Other designs are much larger and do not fit into tight enclosures. Our DP gauges... (read more)

temperatures and feed rates to increase the production of digester gas. Since digester gas applications operate at relatively low pressures, it's essential that instrumentation has the ability to remain accurate in those conditions, a capability that orifice plates lack. Immersible Thermal Mass Flow Meters create virtually no pressure drop and accurately measure these low flow rates. With Sierra's thermal technology installed, Santa Cruz Wastewater can measure true mass flow directly, have outstanding... (read more)
