Hoffer Flow Controls Introductions
The development of the modern turbine flowmeter can be traced back to David Potter, founder of Potter Aeronautical. Potter pioneered the development of the turbine flowmeter for the Navy in the 1940s. The initial application for the Potter turbine flowmeter was in fuel flow measurement for Navy aircraft. Today fuel flow continues to be an ideal application for the turbine flowmeter.
Hoffer Flow Controls was incorporated in 1969 in the state of New Jersey. Hoffer Flow Controls has been designing and manufacturing quality turbine flowmeters and related process instrumentation for more than fifty years. Our initial experience was in the field of cryogenic flow measurement. Today our reputation in this field is synonymous with quality.
Description Hoffer Turbine Flow Meters
Turbine flow meters measure the velocity of liquids, gases, and cryogenic fluids. Typical fluids and gases measured with turbine meters include hydrocarbons, chemicals, water, cryogenic liquids, air, natural gas, and industrial gases. Hoffer turbine flowmeters are simple to operate and maintain. For this reason, Hoffer turbine flow meters can be found in service worldwide and are regarded as a reliable, cost-effective method for achieving high accuracy flow measurement.
Hoffer Flow Controls offers the most extensive selection of turbine flow meters compared to any other flowmeter manufacturers globally. Our MF Series of mini-flowmeters provides flow measurement capability from .007 to 3.5 GPM and offers twelve different turbine meters.
Our HO Series provides ¼” through 12” turbine flow meters for service in either liquid or gas. In addition to the MF Series and HO Series, we provide 20+ specialty series of turbine flow meters.
These specialty series enable Hoffer to offer flow meters suitable for the oil & gas industry, power generation industry, cryogenic industry, military flow applications, and aerospace.
Popular specialty turbine flow meter series include our Grayloc, high-pressure flow meters, the Wafer Series, the Autoclave Series of high-pressure turbine meters, the Subsea Series, and the API Series for custody transfer grade performance and meter resolution (K-factor).
The turbine advantage may be defined as the unique blend of desirable attributes peculiar to the Hoffer type turbine flowmeter resulting in a transducer with the ability to measure wide flow ranges with outstanding accuracy, at low cost, with a convenient pulse output.
Within the Hoffer turbine flowmeter, the flowing media engages a vaned rotor causing it to rotate at an angular velocity proportional to flow rate. The pickup coil senses the spinning motion of the rotor through the housing and converts it into a pulsing electrical signal. The summation of the pulsing electrical signal relates directly to the total flow, while the frequency is linearly related to flow rate.
Performance
The K-Factor is the number of output pulses the flowmeter produces per engineering unit of volume thru-put. The Linear Range is that flow range over which the K-Factor is constant within the specified limits of linearity. Linearity is a measure of the accuracy of the device. The maximum percentage deviation from the average-Factor, K.
The linearity of all Hoffer turbine flowmeters is stated as a percent of reading. Most other metering devices state linearity as a percent of full scale, which implies a derated accuracy.
Each Hoffer turbine flowmeter is individually calibrated, and the resulting performance characteristics are presented in a computerized tabular format. The repeatability of a turbine flowmeter measures the stability of the output under a given set of flow conditions. The repeatability is defined as the allowable percentage deviation from the stated K-Factor at that flow rate.

overlapping ranges. Meter size selection is accomplished with the aid of Chart 1. Flow rangeability requirements often dictate the pickup and bearing type to be used. Note that sleeve bearing selections may reduce the flow range data listed in the flow meter size selector chart but offer extended operating life benefits.
User preference and temperature/pressure considerations determine the turbine flowmeter configuration, and process end fitting types are determined by user preference and temperature/pressure considerations. Standard end fittings include NPT, MS Flared, and flanges in ANSI and DIN standards.
