FT Series
Turbine Flowmeters for Liquid Applications

Description

Flow Technology’s FT Series turbine flowmeters utilize a proven flow measurement technology to provide exceptionally reliable digital outputs. Because of their versatility, these flowmeters are the solution for a wide variety of liquid flow sensing applications. FT Series turbine flowmeters, which range in size from 3/8 inch to 4 inches, offer a high turndown capability, repeatability of ±0.05% of reading, and excellent speed of response.
The precision, axial-mounted rotor design of the standard turbine flowmeter allows it to operate effectively in flow rates from 0.03 to 1,500 GPM, with the linearity rated at ±0.5% of reading over the normal 10:1 turn-down range. All turbine flowmeters can achieve ±0.1% linearity over the full operating range with linearizing electronics. Typical operating pressures for the standard meters are 5,000 PSIG with custom configurations capable of 30,000 PSIG.
A choice of construction materials can be specified for the turbine flowmeter’s housing, rotor, bearings and shaft, including standard stainless steel, and exotic materials for specialized applications.

Features

HS Series
High Shock Turbine Flowmeters


Description

Flow Technology’s High Shock turbine flowmeters utilize a proven flow measurement technology to provide exceptionally reliable digital outputs. Because of their versatility, these flowmeters are the solution for a wide variety of liquid flow sensing applications.
The High Shock flowmeter is specifically designed to withstand pressure spikes that create hydraulic shock waves in the fluid when actuators or rams are activated.
The downstream end of the meter’s housing has a small step, rather than a retaining ring, which prevents internal components from being pushed through by hydraulic shock. The upstream end of the housing includes either a Truark® retaining ring, or in extreme cases, a threaded retaining ring which is screwed into the housing, clamping the internals between the downstream step and the retaining ring. Additionally, the meter’s supports are mechanically locked in place so they cannot rotate in the housing.
The High Shock flowmeter’s rotor blades are thicker than those found on a standard turbine meter. A radius is machined at the intersection of the blades and rotor hub, eliminating the stress point created by a 90-degree cut. In hydraulic fluid applications requiring the use of ball bearings, a step is located in the upstream bore of the rotor so it cannot be pushed over the bearing.
High Shock meters are available in sizes from 3/8-inch to 2-1/2 inches, and are capable of measuring liquid flow rates from 0.03 to 450 GPM (0.1 to 1,700 LPM).
The meters’ standard range is 10:1, but can be extended to 100:1.

Applications

Flow Technology’s High Shock turbine flowmeters are a rugged flow measurement instrument designed for use in environments with high line pressures, hydraulic shock loads and other extreme conditions. The meter incorporates unique features making it well-suited for use in such applications as hydraulic R&D, production testing, and control of rams and valves in the petroleum industry.

Operation

A volumetric device that measures the flow of liquids, the turbine flowmeter’s design is based on a freely-suspended turbine rotor which is rotated by the flow of fluid through the meter body.

Features

• Designed for environments with high line pressures and hydraulic shock loads
• Utilizes special, reinforced rotor blades
• High turndown capability, up to 100:1
• Excellent speed of response
• Repeatability of <±0.05%
• Linearity of <±0.05% of reading over normal 10:1 range for liquid
• Operating pressure determined by end fitting selected
• Liquid flow rates from 0.03 to 450 GPM (0.1 to 1,700 LPM)
• Choice of NPT, MS, SAE 4-Bolt and Dynamic Beam Seal end fittings
• Additional end fittings available as special configurations
