Biogas Meter & Greenhouse Gas Meter Plus: Biogas FT2+

The Biogas FT2+  gas meter provides an extremely accurate instantaneous flow rate and totalized flow for Biogas, Methane, Carbon Dioxide, Greenhouse Gas (GHG), Natural Gas and other gas mixtures.

Advanced solid state electronic technology provides accurate measurement for Greenhouse Gas, Biogas and Methane for maximum Greenhouse Gas Credits and transactions. 

  Ideal Biogas meter or Greenhouse Gas meter.

Accurate Biogas & GHG Gas Measurement = Money!

The model FT2+ thermal mass flowmeter and temperature transmitter measures two important process variables in one rugged instrument with no moving parts.  The FT2+ measures gas flow rate in standard units (SCFM, NM3/Hr, etc) without the need for expensive temperature or pressure compensation.  A 2 x 16 character backlit display is standard to view flow rate, totals, elapsed time, process gas temperature and alarms.  The flow totalizer is non-resettable for use with fuel gas flow measurement of boilers, IC engines and other regulated devices.

The FT2+ is available in insertion and in-line models.  The insertion meter is easily installed by drilling a hole in the pipe and welding on a NPT coupling.  A supplied compressing fitting secures the probe in place.  The in-line model is available several sizes and include a built in flow conditioner that eliminates the need for long, straight pipe runs.  The meter can be ordered with flange or NPT end connections.  Both models are supplied with 316 stainless steel wetted materials standard or Hastelloy C-276 as an option.

AG/Dairy Wastewater Meter - VDP Flowmeter

The VDP Flowmeter provides a solution for AG and Dairy wastewater and discharge water measurement or as part of a nutrient management plan.

The VDP Wastewater Magnetic Flowmeter System consists of the non-blocking flowtube and electronic display. Valley Air Solutions’ Magnetic flowmeters are a cost effective wastewater measurement solution for many dairy, agriculture, cheese plants, and other applications compared to conventional flowmeter technology, because they improve on-site measurement performance and decrease costs associated with maintenance.

The VDP system uses unique sensing technology, which eliminates the large and costly magnetic coils used in conventional magmeters, as well as the need for a flowtube liner. The VDP flowtubes can be constructed from steel or from polyvinylchloride (PVC) to be low cost and lightweight. They are intended for use in plastic pipework in sizes 2” - 12” and steel pipework 2" - 80".
