Typical Applications

The ORIMAS mass flow meters measure the mass flow of most liquids and gases within the process industries, including chemical, petro-chemical, pharmaceutical and the power industry. The ORIMAS is based on the principle of measuring velocity, the static pressure and the temperature in the pipe line. The electronics computerise the mass flow by using the 3 measured values. The ORIMAS flow meters are backed by international standards covering flow calculation, manufacturing tolerances, accuracy and installation requirements. This type of bare bone technology is world wide accepted and supported by millions of successful installations.

Construction

orimas or1

Model Model OR1

The Orimas flow meter model OR1 consists of a primary element based on the differential pressure principle, a 3 valve manifold valve a multivariable transmitter and a temperature sensor. The multi variable transmitter measures the differential pressure, the static pressure and has an input connection to the temperature sensor. The flow computer housed in the transmitter performs the dynamic flow calculation.

Model OR2

The ORIMAS flow meter model OR2 consists of a primary element
and operates as mentioned above but has an integrated 3 valve manifold. The ORIMAS flow meter is mounted between flanges in sizes from DN 40 (11⁄2") to DN 400 (16") in pressure ratings up to PN 40 (300 lbs). Other sizes and pressure ratings on request.

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 witd LCD is available for local flow indication and if required check/change of flow rate (differential pressure).

Principle of Measurement

The ORIMAS is a mass flow meter
A restriction in a pipe line changes the value of the different energies.
Based on the law of energy balance developed by Bernoulli the sum of energies remains constant.
Increases 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 the flow velocity.
The static pressure and the temperature is measured.
When the physical values of the fluid is known and the inner pipe diameter is established the electronics calculate the mass flow. The mass flow is expressed in an analogue signal 4 - 20 mA or signal for digital communication.

Installation Requirements

The Orimas 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. Saturated and superheated steam is covered by STEEMCO flow meters.

Typical Applications

Fast and easy installation in liquid and gas lines requiring minimal interuptions for calibration.
