Original Press Release:
Burkert Introduces Positive Displacement Flow Fitting and Adds Low Flow Sensor for High Viscosity Fluids
0.26gpm to 180gpm Type S070 fitting and 0.5gph to 132gph Type 8071 low flow sensor deliver the high accuracy required in low-to-high flow measurement applications.
Irvine, CA - January 2, 2002 - Users needing to measure the flow of specialty chemicals, food additives, adhesives and other viscous fluids will find an ideal solution in two new positive displacement flow fitting/sensors now available from Burkert.
Both the positive displacement Flow Fitting Type S070 and the positive displacement Low Flow Sensor Type 8071 are specially designed for closed pipe systems to control fluids such as honey or oil with a maximum viscosity of 1,000 centipoise. Applications with erratic flow rates (e.g. after a dosing pump) can be accurately controlled as well. With high accuracy and combined measuring capabilities from 0.5 gallons/hour up to 180 gallons/minute, the flow fitting-with its "Turn & Lock" connection to a wide range of electronics-and the flow sensor can easily be linked to valves and batch/flow controllers via Burkert's EasyLINK technology.
Type S070 Flow Fitting
Burkert Type S070 is an oval gear positive displacement flow fitting that connects easily to a number of Hall or reed switch sensors via a simple quarter-turn technique. With process connections of 1/2-inch to 3 inches (G or NPT) and up to 2 inches ANSI (flanged) this fitting is ideally suited for blending, batching, mixing and dispensing in the chemical, pharmaceutical, water treatment and food industries.
Its operation is based on the positive displacement principle, in which two oval shaped rotors with precisely machined gear teeth rotate within a measurement chamber of specified geometry. As they turn they sweep out and trap a precise volume of fluid between the outer oval shape of the gears and the inner chamber walls. The result is extremely high accuracy (better tha ± 0.5% of reading) and excellent repeatability in the measurement of flow rates from 0.26gpm to 180gpm.
Type S070 is available with 316 stainless steel rotors and shaft in a stainless steel body, or with PPS rotors and stainless steel shaft in an aluminum body. In addition, a limited number of orifice sizes are available with PPS body and rotor with Hastalloy C shaft. It operates in process temperatures to 212°F
(stainless steel body) and 176°F (aluminum or PPS body).
Quick-mounting, Wireless Sensor Interface
Burkert's simple "Turn & Lock" technique allows easy change-out of sensors, switches and controllers to Type S070 without disruption of process flow. The choice of flow control system solutions for Type S070 includes Burkert Type SE30 Hall Flow Sensor, Type SE32 Programmable ON/OFF Flow Switch with integral display and transmitter, Type SE10 reed switch output, and the Type SE35 Programmable Batch Controller or Flow Transmitter.
These interchangeable electronic modules lock into a wireless, inline fitting on Type S070 by a quick quarter-turn. The sensor element in the fitting is completely isolated from the process flow, eliminating downtime. Available in over 25 different variations, the compact electronic modules are ideal for flow
balancing and point monitoring in any type of control system. Modules are carefully matched to the Type S070 fitting to ensure long service life and exceptional performance in most operating conditions.
Type 8071 Low Flow Sensor
The positive displacement Low-Flow Sensor Type 8071 incorporates a non-intrusive Hall-effect sensor and only two moving parts, making it easy to install and maintain.
Threaded process connections of 1/4 inch (G or NPT) make Type 8071 an ideal choice for small capacity, low-to-medium flow applications. Flow rates from 0.5gph to 132gph can be measured with accuracy to ±1% of reading. This flow sensor features 316 stainless steel rotors and shaft in a stainless steel body,
and is also available with PPS body and rotor with Hastalloy C shaft. It operates in process temperatures to 212°F (stainless steel body) and 176°F (PPS body).
Type 8071 Low Flow Sensor can be easily connected to Burkert Type 8025 or flow controller/batch controller Type 8025 (panel or wall mount) with Burkert's EasyLINK technology for lower commissioning costs.
