FloTHERM uses advanced CFD techniques to predict airflow, temperature, and heat transfer in components, boards, and complete systems, including racks and data centers. It's also the industry's best solution for integration with MCAD and EDA software. Measurement Guidelines – Issue 9.2 1: Introduction 1 1 INTRODUCTION 1.1 The Oil & Gas Authority (OGA) The Oil & Gas Authority (OGA) was formed on 1st April 2015, in response to the recommendations set out by Sir Ian Wood in his report (published 24th February 2014), ‘UKCS Maximising Recovery Review’, known as ‘The Wood Review’. The water in the upper flow is mostly of class III based on oxygen regime and nutrients and of class IV based on microbiological indicators, while the water in the lower flow is of class V based.

These flow controls are designed for liquids similar in viscosity to water. All applications should be tested for flow characteristics and chemical compatability to insure desired results. Swelling of the diaphragms in certain liquids will result in loss of flow rate accuracy. An in-line strainer or filter should be installed before the flow control when suspended solids are present, and for all applications below 1.0 GPM (3.8 LPM).
Accuracy:
The rated output of Series FC flow controls will vary ±15 percent with EPDM assemblies.
Materials of Construction:
The standard Series 'FC' flow controls are constructed of TYPE 1, GRADE 1 PVC (Polyvinyl Chloride) with diaphragms of EPDM. Stainless steel fasteners are standard. Bodies are also available in virgin polypropylene, PTFE, and Kynar®. Consult factory.
Operation and Installation:
The Series 'FC' flow controls are used to maintain a constant pre-determined flow in a system. They must be installed in the correct flow direction (indicated by label) to work properly. They utilize a diaphragm which changes shape with inlet pressure changes, thus maintaining a constant flow rate. They are normally used to replace more costly flow control devices. Standard flow ranges are from 1/4 GPM to 120 GPM (.95 LPM to 454 LPM). The minimum pressure drop needed across the flow control is 15 PSI (1 Bar) in order to get the desired flow.
Temperature and Pressure:
The Series 'FC' flow controls can operate from 40 °F - 140°F (5°C-60°C) with PVC bodies and EPDM diaphragms. With optional polypropylene, PTFE, or Kynar bodies they can operate from 40°F- 180°F (5°C-82°C). The Series 'FC' flow controls must have at least 15 PSI (1 Bar) pressure drop across the control in order to deliver the rated flow. Maximum pressure is 120 PSI.

Understandings, applications and skills
| 9.2.U1 | Plants transport organic compounds from sources to sinks. |
| 9.2.U2 | Incompressibility of water allows transport along hydrostatic pressure gradients. |
| 9.2.U3 | Active transport is used to load organic compounds into phloem sieve tubes at the source. |
| 9.2.U4 | High concentrations of solutes in the phloem at the source lead to water uptake by osmosis. |
| 9.2.U5 | Raised hydrostatic pressure causes the contents of the phloem to flow towards sinks. |
