- Page 4 Heliflu TZN Anti scaling — Instruction manual Chapter 1: Introduction to Anti Scaling TZN Meters The simple, rugged construction of Anti Scaling TZN turbine meters provides excellent accuracy and measurement repeatability for a wide range of industrial applications. All TZN flow meters are designed to provide high quality liquid volume measurement across a wide range of viscosities (0.3 to >1,000 cSt).
- Page 5 Heliflu TZN Anti scaling — Instruction manual Generation of Signal The operating principle of helical turbine flow meters is based on the electromagnetic field generated by the rotational velocity of magnets imbedded in blades of the helical rotor passing by a pick-up coil positioned in the flowmeter body.
- Page 6 Heliflu TZN Anti scaling — Instruction manual Chapter 2: Meter Components by Meter Size TZN flowmeters include the following components: Body · Measuring sub-assembly / cartridge · Inlet ring · Detection sub-assembly / Electronics enclosure · Flow conditioner (Optional) · ½...
- Page 7 Heliflu TZN Anti scaling — Instruction manual Meter Body The meter body is most commonly made of carbon steel or stainless steel (AISI 316/316L or equivalent); other materials are available upon request (Duplex, Hastelloy …). The meter body contains a removable cartridge. Depending upon meter size and operational preferences, the body can be fitted with one, two or three bosses, allowing generation of single or dual pulse signals to flow computer, as well as the addition of a localized readout via a totalizer if desired.
- Page 8 Heliflu TZN Anti scaling — Instruction manual Nominal sizes ≥ 16" The 3-piece cartridge is centered and fastened into the body by means of upstream and downstream stainless steel cross pieces containing the rotor. The outer rings are fixed into the meter body to hold the cartridge in place with screws.
- Page 9 Faure Herman can supply the flow conditioning assembly which integrates upstream piping, flow conditioning element (plate, straightening vanes, etc.) and downstream piping (to be utilized at time of meter calibration).
- Page 10 Prior to installing the TZN, visually inspect the turbine meter; pay particular attention to name plate (check for serial number, process conditions, direction of flow …), flange rating and general conditions. Should the product be damaged or documents missing, please contact the Faure Herman Worldwide Customer Support & Service via phone, email or website: Customer Support &...
- Page 11 Heliflu TZN Anti scaling — Instruction manual Handling recommendations: Meter sizes ³ 6"(DN 150) or weighing > 30 kg [66 lbs] The TZN must be carefully handled with lifting rings (when applicable) or with straps on both sides of the body.
- Page 12 Heliflu TZN Anti scaling — Instruction manual Chapter 4: Installation and Operation TZN turbine flowmeters can be installed horizontally or vertically (ascending flow) provided the flow direction indicated on the cartridge and meter body are followed. For custody transfer applications, turbine flowmeters require the integration of a minimum upstream pipe length at least equal to 10 times the pipe diameter and at least equal to 5 times the pipe diameter downstream.
- Page 13 Heliflu TZN Anti scaling — Instruction manual Meter installation Before installation, keep the equipment in its original packing, sheltered from bad weather and possible impacts. The meter should be installed in the measurement line with proper alignment of upstream and downstream flanges so that stress on the equipment body is avoided.
- Page 14 Heliflu TZN Anti scaling — Instruction manual Gaskets Check to ensure that the proper gaskets are installed according to flange type: ASME B16.20 and ASME B16.21 or NF EN 1514 and NF EN 12560 standards. NOTE: Spiral wound gaskets are forbidden for flanges rated below class 300 or PN 63. Never reuse gaskets.
- Page 15 Heliflu TZN Anti scaling — Instruction manual Condition of Liquids Measured Flowmeter life duration and measurement reliability can be seriously impacted by the presence of gas and/or solid particles in the flowing liquid. The presence of gas, in the form of bubbles or emulsions, can cause serious degradation of measurement performance.
- Page 16 Heliflu TZN Anti scaling — Instruction manual IMPORTANT: After a period of critical monitoring, the filtration degree can be relaxed to reduce strainer maintenance and pressure losses, e.g. MESH 6 to MESH 4 on a 12” meter (consult manufacturer). Should a filter and air elimination system be used simultaneously, we recommend placing the air eliminator as the last device upstream of flow conditioning.
