Flemco Flow Meters F1&F2

flemco

The EMCO compact orifice range of flow meters measure most liquids and gases.The FLEMCO meter is a compact orifice assembly designed to slip between DIN and ANSI flanges, and is designed for compact mounted dp cells. With an installation length of 32mm it can be installed in existing systems simply and easily, and incorporates the dp flow priciple. d.p. metering enables easy re-calibration routines for process operators, negating the need for expensive flow metering spares and external flow recalibration services.

Typical Applications

The FLEMCO flow meters measure the flow of most liquids and gases within the process industries, including chemical, petro-chemical, pharmaceutical and the power industry.

The FLEMCO is based on the principle of measuring velocity in the pipe line,therefore the flow measurement is volumetric.

The FLEMCO flow meters are backed by international standards covering flow calculation, manufacturing tolerances, accuracy and installation requirements.

This type of bare bone technology is accepted world wide and supported by millions of successful installations.

Accessories

Remote Mounting Kit type RMK is available if remote mounting of electronics is required in case of difficulty accessibling pipeline or if there are elevated process temperatures. The customer has to provide the stainless steel instrument tube Ø 12 x 1 mm between flow meter and electronics. Remote electronic indicator with LCD is available for local flow indication and if required check/change of flow rate (differential pressure).

Principle of Measurement

The FLEMCO is a velocity flow meter. A restriction in a pipe line changes the value of respective momentum energies, in terms of static and dynamic pressure. Based on the laws of energy balance developed by Bernoulli, the sum of the energies remain constant. Increasing the velocity in the pipe line, decreases the pressure in the restriction. The pressure differential between the inlet pressure and the pressure in the restriction is measured and expressed as flow velocity. When the physical values of the fluid are known and the inner pipe diameter is established the electronics calculates the flow rate. The flow rate is expressed in an analogue signal 4 - 20 mA signal or via digital communication.

Installation Requirements

The FLEMCO flow meter can be mounted in a horizontal or vertical pipe. For liquid flow in a horizontal pipe the electronics shall be mounted below the pipe. For gas flow in a horizontal pipe the electronics shall be mounted above the pipe. To insure high accuracy of measurement, long straight pipe runs up-stream from the flow meter is necessary. The required straight pipe run depends on the disturbance upstream. To maintain the 1% accuracy the minimum straight pipe run upstream shall be 14 x inner pipe diameter and 6 x downstream If an additional inaccuracy of 1⁄2 % is acceptable the required straight pipe runs are reduced to half of the above values. If mass flow required due to changing process conditions ask for the ORIMAS mass flow meter data sheet. Saturated and superheated steam is covered by STEEMCO flow meters
